Serves 4, with leftovers
Saute onion and garlic in olive oil until translucent. Add burger and brown.
Add tomatoes, paste, and spices. Turn heat down, cover sauce and simmer 1 ½ hours. Add mushrooms and liquid after 1 hour.
Serve sauce over cooked pasta.
Mom usually made twice this quantity for the 8 of us. I still make that much and freeze half for the future.
I usually "update" this by replacing the canned mushrooms with some fresh mushrooms cooked with the onions and garlic, and by using very lean meat to minimize the fat. I sometimes substitute Italian sausage for half the meat.
