Crock Pot Pulled Pork

• 1/2 cup ketchup
• 1/3 cup worcestershire
• 1/3 cup apple cider vinegar
• 1 Tbsp ground mustard
• 1 Tbsp garlic powder
• 1/2 tsp paprika
• 1/4 cup brown sugar
• dash red pepper flakes
• pinch salt and pepper
• 1 medium onion, chopped (we chop into big chunks to remove after cooking)
• 3 pounds pork tenderloin
• Hamburger buns
• BBQ Sauce (optional)

Combine all ingredients except onion and pork into crock pot. Whisk until well blended. Place pork and onions into mixture, coating both sides of meat. Cook for 8-10 hours on low or 6 hours on high. After meat is cooked, shred with forks inside the crock pot and stir into the sauce. Serve on hamburger buns or rolls, or by itself on a plate, with optional bbq sauce to top.
