A tuna melt with creamy tuna on top of half a tomato draped in melted cheese. With or without a pickle!
Heat your oven to 400 degrees. Slice the tomato in half and scoop out the seeds. You dont have to do this, but if you leave the seeds in, it can get runny. OR you can just use big slices of tomato.
Open the can of tuna, scoop it into a bowl, add the mayo and the green onion. Stir to combine. Or you can just squirt the mayo on top too.
Place the tomatoes on a parchment lined baking sheet. Put half the tuna mix on each tomato half. Top each tomato half with pickle slices and then the cheese.
Bake in the oven for about 15 mins or until cheese is melted and bubbly. Remove from the oven and serve right away.
You can use any kind of cheese for this as long as it melts well. I just really like Gruyere and Cheddar.
For an option, try a few slices of avocado instead of the pickle. Or try both!
