Boil cabbage leaves in water and beef broth until semisoft (be able to roll like a tortilla.) do not dispose of water. Season ground beef with salt/pepper; add minced garlic cloves and diced onion. Brown lean ground beef. Add ground beef to cabbage leaf and roll. Place in a 10 x 13 baking pan. It will resemble regular enchiladas. Add tomato sauce and beef broth to water used to boil the cabbage. Pour small amount over the cabbage rolls, about 1/8" of baking pan. Add cheese!! All you want! Bake until cheese is melted and it's ready!!! Add sliced avocado on top of enchiladas.
