BBQ Pulled Chicken Sandwiches

I own a crock pot and rarely get use out of it except sometimes when I make meatballs during football season. So right before school went back in session, when I was home for a few more long summer days, I decided to utilize my crock pot and make some bbq pulled chicken! It came out SO delicious and it was so easy to make. I'm definitely going to make them again very soon.
The recipe was kind of a compilation of several recipes I found online where I could use things I already had in the house. It seems like the kind of recipe where you could add in whatever you wanted to your liking. Here is what I used:

Ingredients
3 boneless chicken breasts
1/2 cup ketchup
1 bottle of your favorite BBQ sauce (I used a honey BBQ sauce)
2 tbs of brown sugar
1/4 cup water
1 package of Hawaiian rolls or regular sized rolls

Directions
Place all ingredients in crock pot and mix around with spoon. Make sure chicken is covered by the liquid. If not, you can add some more water until chicken is immersed.
Cook on low for 5 1/2 hours
Take chicken out of crock pot and shred/pull apart with 2 forks
Put pulled chicken back in crock pot and re-warm for about 10 minutes
Serve on rolls!
