Prepare the homemade crust. Or buy them from the store. (But homemade are so much better!)
Cut up the chicken breast into bite size pieces and then add them to a skillet with the BBQ sauce and about 1/2 cup of water. Bring to a simmer, then cover and cook over medium heat until the pieces have cooked through and are coated with BBQ sauce. Will take 5-10 minutes, depending on size of the pieces.
Spread the pizza sauce over the large pizza or smaller ones. You don't want it to be too much and let the tomato flavor over power the other flavors.
Add the cooked chicken pieces, the diced red onion and cilantro leaves. Sprinkle the cheese over top.
Bake at 350 for 12-15 minutes, or until crust has cooked and the cheese begins to golden.
Slice, serve and be merry!
