Brown ground beef and sausage together; drain. Cube the cheese and melt into the meat mixture. Add seasonings. Simmer 1 to 2 minutes. Place 1 tablespoon onto each slice of party rye; place on baking sheet. Bake at 375 degrees 8 to 10 minutes or until bubbly. If you plan to make ahead, put the mixture on the rye bread, place on baking sheet and freeze. Once they are frozen, put them in plastic bags and keep in freezer. You can then take out as many as you want and pop into the oven.
