Left overs really are your friend. We were losing a ton of money throwing food away. Buy what you will eat and eat what you buy.
make a menu and stick to it, seriously it helps
We had hamburgers and french fries, lots of fries left over, they get chopped up and go into the taco meat the next day. The taco meat goes inside egg roll wrappers for fried burritos the next day, with cream of mushroom soup on top. It is an ongoing surprise to my kids, what to do with what they don't eat.
When they begin to look at me with that, oh no, mom not that again, It goes in a freezer bag for a few weeks from now, where it will be resurrected! bhahah
Nine here, and 4 teens! Crazy amounts of food, so I pad the meat with rices, potatoes, and noodles, yes I do. I have been known to pour instant mash pots in sauces, and with hamburger meat.
We eat avlot of vegis with cheese as a main meal. NO meat. Zuchini and Squash seared with onions and cheese, yums
Beans are at least once a week, and I make a ton, cause those babies are going in everything thru the week!
Saturdays are fend for, I pull all the containers out of the fridge, and it is a first come (thee who has finished chores first) first served. They can all push the buttons on microwave, and it is a free for all!
