Easy Sloppy Joe Pot Pie

Found this at the Betty Crocker website - looks good, something the kids will eat, but it's a little different than normal. I can't tell you how many times I put homemade sloppy Joes on the menu and forget to get buns!

Makes 6 servings.

1 pound ground beef
1 medium onion, chopped (1/2 cup)
1 can (15 1/2 ounces) original sloppy Joe sauce
1 cup shredded Cheddar cheese (4 ounces)
1 cup Original Bisquick
