When Greg’s working in the garden or tending the smoker all day, I like to whip us up something fun for lunch. It’s never too fancy, maybe quesadillas with leftover grilled vegetables or, hmm, OK that’s pretty much my specialty. But I did concoct these with some tomatoes from our garden. This makes a nice lunch for two. Double as needed.
Stuffed tomatoes
- 2 good sized tomatoes (sliced in half, seeds removed)
- 2 cans tuna in oil (reserve oil from one, if you only have water packed add 1 tbsp olive oil)
- 2 tbsp breadcrumbs
- 1 tbsp Dijon mustard
- 1/4 cup Romano
- 1 tbsp salted capers
- ground black pepper to taste
- four slices melting cheese (we like cheddar)
Mix ingredients together and divide between four tomato halves. Top each with a slice of cheese and place in a lightly oiled pan. Put in the broiler until cheese is melted. You can cook a bit longer if you want the tomato to roast, but be careful not to overcook.

Thanks, I can never have too many tomato recipes as I just love them. My family would love this one!
Clever idea using tuna, especially with oil…yum! I’ll add egg in my tomatoes and bake them, add your favorite spices and cheese, makes a great breakfast! I’ll have to try your recipe Katherine, I know my husband and I would enjoy it!
Oh… Tomatoes, capers, tuna! Three of my favorite things. I am definitely going to have to try this.
Love these, always a great lunch time break treat!Delish!
Gorgeous recipe. This is a wonderful meal !!
Delish – and a very beautiful tomato, if I might say!
It looks at least as delicious as the tomatoes stuffed with ground meat, but much easier and quicker! Thank you for the idea! What does “Romano” mean? Is it a kind of sauce or cheese? (I have just googled and found both).
It’s a kind of cheese. I always use it instead of Parmesan. Katherine likes both, but I really prefer Romano.
Thanks Greg! Maybe you mean pecorino romano? It has a similar consistency to parmiggiano, but is whiter and of course has a different taste…
Yes, that’s exactly what I mean. I always just say romano for short! I like it more.
So simple yet so fancy. Love this!
simple perfection!
Mmmm….this looks great!
I don’t know why I’ve never put capers in tuna salad. This looks wondertul and a perfect summer treat.
Hi Katherine! This looks good and quick and easy. I can’t wait for my tomatoes to get ripe. I have lots of green ones but no ripe ones yet. This will be on my table for lunch soon.
Summer tomatoes top the list for lunches around here, gotta enjoy them at their peak.
Tuna is so delicious and I like it here in the juicy tomato – a nice seasonal change from bread. The capers sound great too. Yum!
These sound perfect – I’ll be sure to try this!
Stuffed tomatoes are the best. I’ve never done it with tuna, but that sounds like it’d be delish. Awesome recipe, Katherine!
I love capers! This looks delicious!
I like this! Tuna and capers are such strong flavours, I’m totally intrigued!
Yum! definetly a muct try!
that was supposed to be (must)
Mm, tuna and capers makes a delicious combination, especially with some good olive oil! Did you ever try adding in some chopped coriander (cilantro) too? Really delicious!
That was the first time she did that, so not so far. Sounds intriguing though!
I love roasted tomatoes with a garlicky bread crumb topping but never thought to add in tuna! Sounds like a great lunch idea. I believe in the less fancy the better!
I cannot get enough tomatoes (or capers) in my life right now!
Ha, I can never have enough capers or tomatoes in my life!
Looks great! Is that a polka-dot plate? Cuteness!
I might have to try this with the salmon and fontina I have on hand…
There’s no way I could get hubby to eat this (he hates tuna outside of sushi) – it looks fantastic though!!! Perhaps with the above suggestion of salmon…maybe then I could get him to go for this. Very fun lunch!
That looks delicious and I love my tomatoes! I really need to stop looking at your blog when I am hungry ..
I am so envious that you can make dishes using what you’ve grown – looks sooo good ! May I have your quesadilla recipe please ?
Ha, I don’t have one. I just use whatever I have on hand. Try to put fresh veggies, some burrito sauce on there. Katherine loves using grilled veggies.
Gorgeous looking tomato with yummy stuffing!!! What else can you ask for??
Hi Katherine, I’m sure that your stuffed tomato made a perfect lunch for the two of you. And much more imaginative than plain tuna fish salad in a tomato that you see so often in the summer.
Thank you once more, Greg! Now that I know all the ingredients, it’s time to roast the tomato
Ooh yum! Tuna with tomato beans and cucumber is pretty much on my lunch menu everyday – this mixes things up a little with the cheese and serving the lot warm. Great idea!
I’ve never made stuffed tomatoes, so I will have to try these out!
Wow! My family’s stuffed tomatoes are nothing compared to these! Although I’m still weeks away from picking my own, I’ll be giving your recipe a try once I can.
Thanks, a lot of people do cold tuna salads, but I hate mayo. So I wanted more of a tuna melt.
Good Lord these look great! Tuna is such a great protein for this heat, I am making these this week! Thanks for sharing.
looks amazing! It reminds me of a dish I tried in Bosnia, they are known for stuffing everything!
Am so excited to see more of your travel posts!
One of my favorites and a beautiful picture too….RaeDi
I love a recipe that has all the “food groups” in one:) Yummy!
