How to Make It
Place a pizza stone, pizza pan, or large baking sheet on middle rack in oven. Preheat oven to 500°F (do not remove pizza stone while oven preheats). Cook ground beef in a large nonstick skillet over medium-high, stirring until crumbled and no longer pink, about 7 minutes. Stir in taco seasoning and water; bring to a boil. Reduce heat to medium-low, and simmer until thickened, 3 to 4 minutes. Set aside.
Stir together beans and salsa in small bowl.
Roll dough out into a 14-inch circle on a lightly floured surface. Transfer dough circle to hot pizza stone, and, working quickly, spread bean mixture over dough, leaving a 1-inch border. Top with ground beef mixture and cheese.
Bake at 500°F until cheese is bubbly and lightly browned, 9 to 10 minutes. Remove pizza, and let stand 5 minutes. Stir together sour cream, lime juice, chopped cilantro, and salt; spoon over pizza. Top with tomatoes, pickled jalapeños, and cilantro leaves.
