Cook enough ground beef for however many you want to make. Take out hamburger rolls and split each in half. Roll each piece out till flat. Once ground beef is cooked mix with desired amount of ketchup.
Place rolls in a muffin tin. Bake till warm and edges are a little crispy. Fill with meat and a small piece of bacon. Place back in the oven till bacon is cooked. Top with a pickle slice. Serve and enjoy!
