Buy a Crock Pot. There are these Crock Pot Classics for about $5, sometimes $4 on sale.

My wife works and we get one about once a week.

I scramble eggs, cook bacon, and put all of it in a tortilla with some hot sauce.

Pre-made salad bags, about $1.50 to $2. Cantelopes are still in season in Texas, they don't last an hour in the house with a 5, 8, and 10 year old.

Frozen pizza, but we buy the "good" kind, or supplement it with extra cheese.

My wife and I like the stir fry skillet chinese, but the kids don't.

Ask for a "George Foreman" grill for Christmas and some pre-patted hamburger meat.

Of course, all this assumes that you're not a vegaterian or some other dietary restrictions for you or the kids.
