Heat oven to 425 degree F. Divide dough into 4 pieces. On a floured surface, pat or roll each piece to a 4-inch circle. Place on a greased baking sheet. Poke each piece all over with a fork, brush with oil, and bake for 8 minutes.
Spread hot crusts with barbecue sauce and top with chicken, chopped pepper, and cheese. Bake another 8 minutes, or until golden.
