Preheat oven to 450F. Flour the work surface and evenly roll out dough to roughly 12-in across. Combine drained black beans and Ro-Tel in a bowl. Spread on top of dough. Top with cheese. Distribute veggies evenly. Bake until cheese has melted and crust turns crispy and lightly browned, approximately 10-15 minutes. Serve with cilantro and avocado. Lime juice really brightens up the dish.
