I started using TVP, textured vegetable protein in most of my meat cooking. It looks a bit like oatmeal. Use about a 1c to 1 1/2c in a meat sauce, or a 1c + 1c water, let rehyd in lean ground meat, it has no fat but all the protein. TVP is tasteless, it takes on the favors you add, wonderful stuff.
You can find TVP in most health stores and grocery stores
