Pulled pork, North Carolina style BBQ

2 medium onions, finely chopped (yes, needs a lot of onion)
1 T canola oil
6 garlic cloves, minced (fresh garlic is much better than dried)
1 t. crushed red pepper flakes (try half this amount if you like it mild)
1 t. pepper
1 can (14.5 oz) diced tomatoes
1/4 c. packed brown sugar
1/4 c. cider vinegar
2 T. hot pepper sauce (try half this amount if you like it mild)
1 T Worcestershire sauce
1 t. ground cumin
1 boneless pork shoulder butt roast (3-4 lbs, if it's larger you may need to up the other ingredients)
8 Kaiser rolls, split

1. Saute onions in oil until tender. Add garlic and cook 1 more minute. Add everything else except meat and rolls. Cook over medium heat until heated.

2. Cut roast in half and add to slow cooker. Pour sauce over the top. Cover and cook on low for 10-12 hours. Remove roast, skim fat, shred meat with two forks when cool enough to handle and return to slow cooker.

3. Serve on a bun with sweet pickles.
