1Heat oven to 350°F. Separate dough into 8 biscuits. On ungreased cookie sheets, press or roll each biscuit to form 5 1/2-inch round.
2In medium bowl, mix chicken, beans, salsa and taco seasoning mix. Spread evenly over biscuits to within 1/4 inch of edges. Top evenly with onions, bell pepper and cheese.
3Bake 20 to 24 minutes or until biscuits are golden brown and cheese is melted, reversing position of cookie sheets halfway through baking time. If desired, garnish with sour cream and guacamole.
