Pulled Pork Sandwiches

2 1/2 to 3 lb Boneless pork sirloin roast
1/2 tsp Salt
1/2 tsp Black Pepper
1 Tbsp Vegetable oil
2 medium Onions, cut into thin wedges
1 cup Root Beer
2 Tbsp Minced garlic
3 cups Root beer (two 12 ounce cans)
1 cup bottled Chili sauce
1/4 tsp Root beer concentrate (optional)
6-8 dashes hot pepper sauce


Trim fat from pork roast, if necessary.  Cut meat to fit into slow cooker.  Sprinkle with salt and pepper.  In a large skillet, brown the pork roast on all sides in hot oil.  Drain off fat.  Transfer meat to slow cooker.   Add onions, 1 cup root beer and the garlic.  Cover and cook the mixture on low heat setting for 8-10 hours or on high heat setting for 4 to 5 hours. 
Meanwhile, for sauce: in a medium saucepan, combine the 3 cups root beer and the chili sauce.  Bring to boiling, reduce heat.  Boil gently, uncovered about 30 minutes or until mixture is reduced to 2 cups, stirring occasionally.  If you like, stir in root beer concentrate and hot pepper sauce.
Remove the meat and onions from the cooker with a slotted spoon.  Discard cooking liquid.  Using two forks, pull meat apart for shredding.  Serve on your favorite bun.
