Pasta bakes- I boil penne or ziti pasta, and while that's cooking, I sautee mushrooms, onions, bell peppers, or whatever else I have on hand. Once the pasta's done, I drain in and put in in a casserole dish, then layer on the sauteed veggies, as well as other veggies (like olives or broccoli), pepperoni slices, and a jar of spaghetti sauce. Then I top it all with cheese and bake it for about 10 or 15 minutes at 350, until the cheese is melty.
These are nice, because you can put anything in that the kids like (or leave out what they don't like!)
Breakfast for dinner- Pancakes, bacon, eggs or omlettes, fresh fruit.
