Crockpot Pork Loin Sandwiches

1 pork loin
1 onion, sliced thinly
1 c. chicken broth
2 T ketchup
1/4 c. brown sugar
1 T minced garlic
2 tsp. worshershire sauce
BBQ sauce

Mix chicken broth, ketchup, brown sugar, garlic, and worshershire sauce in crockpot. Put in onion and pork loin. Squeeze BBQ sauce on top of pork. Cook on low for 6-8 hours. Take out and shred then put back in sauce for a little while so it can soak up all the juices. I like to have mine on a hamburger bun with a little more BBQ sauce.
