It would help to know some of the things you like to eat, but here are a few ideas I've saved from previous questions like this:
Cook ground beef with garlic, onions and peppers and freeze. Later, thaw and (or do for dinner tonight):
* Add pasta sauce and serve with spaghetti, salad and garlic bread
* Add 1 cup salsa, a small can of tomato sauce, a can of black beans, 1 cup frozen corn, mix together in casserole dish, top with prepared cornbread mix and bake
* Add taco seasoning and 1 cup salsa, roll up in flour or corn tortillas, top with can of enchilada sauce and shredded cheddar and bake
* Add can of Sloppy Joe sauce and serve on burger buns or rice
Quesadillas - make with shredded rotisserie chicken and Monterey Jack or cheddar cheese, serve with salsa and sour cream.
Rotisserie chicken, prepared mashed potatoes, jar gravy, steamed frozen green beans sprinkled with seasoned salt.
