The BEST Baked Beans

I kid you not, these baked beans are fantastic. I took them to the family Easter Egg hunt and they were a big success. Here is the recipe:

1 lb bacon (cooked until super crispy and broken up)
1/2 lb hamburger -cooked(optional; I didn't put it in mine)
2 large (27 ounce) or 4 small cans pork & beans
1 large (27 ounce) can stewed tomatoes (blended to eliminate chunks)
1 large onion-chopped and sauted in 1 Tablespoon bacon grease
1 cup brown sugar
1-3 teaspoons prepared mustard (to taste)
1/2-2 teaspoons liquid smoke (to taste)
fresh ground black pepper (to taste)

Mix all of the ingredients in large bowl. Pour into 9x13 pan and bake, uncovered, for 1-1 1/2 hours at 350 degrees.
