When I get home from grocery days I usually set aside some prep work time see this post . Part of my prep work also include pre-cooking ground meat . For any recipe that call for hamburger I use a 50/50 mix of ground beef and ground turkey. To cook it quickly, in large quantities and to climate even more fat, I boil it! You just put the whole thing in a large pot, coo and drain. Then package into zipper bags and freeze for later use- this saves, fat, time, money (turkey is cheaper) and freezer space!
