Here is a recent food stretching technique I've started using to try and make my meat last longer. One of our local grocery stores will periodically run a sale where ground beef is actually cheaper than ground turkey as long as you purchase packages of 3 (or 5) pounds or more. I try to catch this sale and take advantage of it. When I get home, we will take our 5 pounds of beef and divide it into 6 units making the meat that SHOULD last for 5 meals into enough meat for 6 meals.
Try it. I bet your family doesn't notice the absence of that quarter pound of ground meat and you get an extra meal from it.
