Unroll pizza dough and place pizza dough (and parchment paper) on top of a baking sheet or pizza pan. Par-bake the dough for 10 minutes.
Meanwhile brown the ground beef and onion in a skillet over medium heat, until no longer pink. Stir in the taco seasoning and cook an additional minute.
Remove pizza crust from oven and top with the warmed refried beans and smooth into an even layer. Sprinkle with cheese and taco meat. Return to oven for an additional 6 to 7 minutes, until pizza crust is golden brown and cheese is melted.
Top with any optional toppings you would like! Enjoy!
