Pulled BBQ Chicken Sandwiches

I retrieved this recipe from Ellie Krieger's cookbook, So Easy. This recipe really is easy. Using a rotisserie chicken helped this recipe come together for a perfect weeknight meal. I loved the sauce! I added a bit more molasses to it because it is one of my favorite things, so good and healthy!

Source: So Easy by Ellie Krieger

1 tablespoon canola oil
1 large onion, chopped
3 cloves garlic, minced
1 (14-ounce) can low-sodium tomato sauce
1/4 cup tomato paste
1/2 cup water
1/3 cup apple cider vinegar
5 tablespoons molasses ( I added 1 more tablespoon)
1/4 teaspoon ground black pepper
1/2 teaspoon liquid smoke ( I omitted)
1 whole rotisserie chicken, skin removed, meat shredded into thin strips (about 4 to 4 1/2 cups)
6 whole-wheat hamburger rolls
6 large green lettuce leaves

Directions:
Heat the oil in a large saute pan over a medium heat. Add the onions and cook until they are soft and translucent, about 5 minutes. Add the garlic and cook for 1 minute more. Add tomato sauce, tomato paste, water, vinegar, molasses, pepper and liquid smoke and bring to a boil. Reduce heat to medium-low and simmer for 15 minutes. Add chopped chicken, return to a simmer, and cook an additional 10 minutes.
Split rolls. Place a leaf of lettuce on each roll, then pile on 3/4 cup of the chicken mixture onto the roll.
