Purchase ground beef in bulk for the best price. Prior to freezing, make the entire package into hamburger patties. My preference is 1/3-pound, but you can make 1/4-pound.
Place the patties on a cookie sheet and freeze. Next stack in a freezer bag separated by wax paper. These patties are easy to defrost in the microwave or thaw quickly when you plan ahead.
You can make hamburgers, hamburger steak with gravy and onions, defrost multiples for a casserole requiring one pound, etc. One of my favorite meals is to take one patty, brown the beef, add a can of black beans, and use it for an economical meal of nachos or tacos.
This helps to get a meal ready with very little notice. Janice
