Optional: You can use any or all of these if you want – canned beans, sliced mushrooms, peppers (green, red or orange), celery, canned corn kernels
In frying pan, brown the ground beef with the onions. (Add mushrooms, peppers, celery now if using.)
When the beef is no longer pink and the onions are translucent, stir in the BBQ sauce and ketchup. (Add the canned beans now if using.)
Spray a small casserole dish or glass baking dish with cooking spray and spread the beef mixture on the bottom.
Lay the biscuits around the top of the beef mixture, cut side down. Try to cover all the meat.
Sprinkle shredded cheese on top of the biscuits and bake for 20 minutes.
Check after about 7 or 8 minutes to make sure the cheese is not burning. (If it’s getting too brown, remove the dish and cover loosely with foil before putting back in oven to finish cooking.
Remove from oven (remove foil if using) and let sit for a few minutes before serving.
