Preheat your oven to 400 degrees.  In an 10-inch oven proof skillet (mine is more like 12-inch), brown the beef and onion together until beef is no longer pink and onion is tender; drain.

Add sloppy joe sauce to the meat and stir to combine. Remove from the heat and sprinkle with 1 cup of the cheddar cheese.

In a small bowl, mix together the baking mix, milk and egg until combined.  Pour over the beef mixture.

Place the skillet in the oven and bake at 400 degrees for 30 minutes or until golden.

Remove from the oven and sprinkle with the remaining 1/4 cup of cheese.  Makes 4-5 servings.
