In a cast iron skillet, cook the ground beef until no longer pink. Next add the black beans, salsa,and cheddar and combine. Let simmer while preparing the dumpling batter.
In a bowl combine all of the ingredients minus the cheese. Once well combined, stir in the cheese.
Drop large spoonfuls of the batter on top of the beef (should make about 6 dumplings) and put skillet into a 350 degree oven for 20 to 25 minutes.
*If you don't have a cast iron skillet, cook the beef, add the salsa and beans, then transfer to a baking dish before topping with the dumplings and baking in the oven.
*Serve with a dollop of sour cream.
