I love french fry...and tater tot casseroles.
Super easy....1 lb ground beef browned / mixed with onions (if you like).
Some frozen peas, corn...whatever vegetable you like mixed with 2 cans (cream of whatever) soup.

(I change the recipe whenever I feel like it for variety.
Put in casserole...top everything with fries or tater tots and cook until brown.
Seriously yummy!
