Lindsey's Pulled Pork Sandwiches

I got this great recipe from my friend Lindsey...I tweaked it a little bit with another recipe she gave me and it turned out so good!

4 1/4 cups ketchup

1/4 cup butter

1/3 cup vinegar

3/4 cup brown sugar

1/3 cup white sugar

1/4 cup grated onion

1/4 tsp garlic powder

3/4 tsp pepper

2 T. Worchestire sauce

1 tsp. chili powder

Cook your 4-5 lb pork roast (I used two pkgs of pork loins you can get at Costco)) in a crock pot for about 5-6 hours.  (I salt and pepper the pork and added some garlic powder and Nature's Seasoning Blend to give it a little seasoning).  Meat should just fall apart and be easy to shred in the crock pot.  Combine all the above ingredients and simmer on the stove for 30 minutes.  Pour over cooked meat.  Serve on rolls.   So easy and so good!
