2 lb. pork tenderloin cut in half crosswise. In a large stock pot, brown 2 thickly sliced sweet onions in a little olive oil. Brown both pieces of the pork on all sides.
Season with garlic powder, ground black pepper, cayenne to taste. Add 1 bottle of Pilsner Urquel beer, or other Oktober brew of your choice. Bring to boil.
Turn to low and add spicy barbecue sauce of your choice. I used Maple Chipotle and a little Sesame Sriracha. 2 cups total. Cover and simmer for 4-6 hours, until meat is easily pulled apart.
Pour out excess liquid. Pull the meat and put back into stock pot. Add more barbecue sauce to taste. Add 1 can Great Northern white beans. Simmer uncovered for another 1/2 hour.
Serve over braised red cabbage.
