I know you don't usually think of tuna as "comfort food", but this casserole is awesome, and the tuna isn't overpowering. Way simple too! My kids love this... but I don't tell my boys there is any tuna in it, tee hee!
1/2 lb uncooked pasta
1 can tuna, drained
1 C chopped broccoli, fresh or thawed & drained
minced onion, optional
1 can condensed cream of mushroom soup
1/2 C sour cream*
1/4 C milk
2 C shredded cheese, divided
Preheat oven 350 degrees. Cook pasta in pot over stove; drain and pour into 2 qt casserole dish. Add tuna, broccoli and onion (if desired). Toss well. Fold in soup, sour cream and milk, one at a time. Add in HALF the cheese. Stir well and spread evenly in pan. Bake about 25 minutes. Top with remaining cheese and bake another 10-15 minutes until cheese is melted. Serve warm.
*you may also omit sour cream and increase milk to 1/2 C.
