When you buy a new loaf of bread, take the stale loaf and make up a bunch of peanut butter & jelly sandwiches. Don't forget to measure and use lower fat, lower sugar ingredients. :) Put them in individual sandwich ziploc bags and freeze them. Any time you need a quick grab n go meal, you can pop one in the toaster oven for 5 minutes, and you have a great toasted PBJ. You've saved money (didn't throw out the bread, didn't buy meal bars), and you know exactly what you're eating. And yummy!
You need a toaster oven.
