Pesto Tuna

1 can of tuna (albacore preferred, but I used regular)
1/2 tomato, diced
1 Tbsp shredded Parmesan cheese
1-2 Tbsp olive oil mayo
1-2 Tbsp basil Pesto
dash of salt
dash of pepper

Mixed it all together in a bowl.

Toasted half a whole wheat bagel, placed about half of the mixture on top of the bagel, topped with sliced sharp cheddar and broiled for 1-3 minutes. It was delicious and I could eat it at least 3 times a week (that's a lot).
