Cook lots of food. Way more than your family can possibly eat in one night (I realize this is probably easier with smaller families). Then you can have leftovers, and you'll only need to cook every other day.
Don't like leftovers? While some things are fine to serve again as they are, sometimes you may need to turn your leftovers into "new food." Here's a short list of foods that can easily be made with leftovers.
- Soup: Shred or cube meat and/or veggies. Simmer with some broth or stock, or put it in the slow cooker. BAM! New food. Crusty bread really takes this to the next level.
- Pasta dishes: Again, cube meats or veggies. Toss with a jar of sauce and some noodles. To really fool 'em, top with cheese and heat through.
- Quesadillas/nachos: Cheese, tortillas or chips, and leftovers. That's it. You could also make burritos using basically the same principles.
- Loaded potatoes: Bake some taters (in the microwave for even more speediness) and top with leftovers. Use big potatoes and put a veggie on the side to make these a whole meal.
See how easy this is? Now you can cook every other night!
