1. Cook pork in a large skillet over medium-high heat 5 minutes, stirring until meat crumbles and is no longer pink; drain well on paper towels. Wipe out skillet with a paper towel. Return pork to skillet; stir in taco seasoning mix and 2/3 cup water; cook according to package directions on seasoning mix. Remove mixture from heat, and stir in chopped cilantro and next 3 ingredients.
2. Place pizza crusts on baking sheets. Spread half of beans evenly over each crust, leaving a 1/4-inch border around edges. Top beans evenly with pork mixture.
3. Bake, 1 pizza at a time, at 400° for 8 to 10 minutes or until thoroughly heated and cheese melts. Remove from oven, and let stand 5 minutes. Serve with desired toppings.
*1 lb. ground chuck may be substituted for ground pork.
