Brown and drain the Hamburger. Add both cans of Pork & Beans. Fix well. Add as much or as little of the three BBQ sauces to the mix. Again, mix well. Add Ketchup and Mustard to taste. Once all is mixed, add a handful of chopped onions (the finer the better). Let simmer on low heat for 15 minutes. Make your Rollout Biscuits. Cut out in circles. Cut circles in half giving two half circles. Stir the Beans & Hamburger. Arrange biscuit halves on top of simmering beans. Stand biscuit halves on end so that round halves are up. Cover the complete top of the beans and hamburger mix with biscuit halves. Add all shredded cheese on top of biscuits. Bake for 30 minutes at 400 degrees. It's done when the biscuits are done.
