Hamburgers: I use 3/4 pound lean ground beef with 1/4 cup pureed red beans and 1/2 cup each finely grated vegetables like onions, carrots, summer squash, ect- what ever we have on hand. I can make up 7 nice large hamburgers with this and even my picky eaters love them. Next to no fat and very juicy! Beans add extra protein but don't add to much or it changes the texture. We add pureed beans to all our ground meats.
