Preheat oven to 450 degrees F. Spray a 12-inch pizza pan with cooking spray. Sprinkle with cornmeal.
Combine Bisquick and cold water in a small bowl. Pat out mixture onto bottom of pizza pan until uniformly covered and flattened out. (Or roll the Bisquick mixture out into a circle on a flat surface and transfer to pizza pan) Crimp edges up and poke a few times with a fork.
Brown meat; drain any fat. Add 3/4 cup water, chilies and taco seasoning. Bring to a boil. Simmer uncovered 15 minutes or until thickened.
Spread beans on dough. Top with meat mixture. Bake 20 minutes. Top with cheese and return to oven until cheese is melted. Cut like a pizza and serve with or without toppings. ENJOY!
