This flavorful tuna casserole is a family-pleaser you'll make again and again. Serve tuna casserole with a tossed salad for a perfect meal any day of the week.

Shredded cheddar cheese makes a tasty topping for the casserole, but feel free to use a cheddar jack blend or half American process cheese. Add extra cheese if you like!
