# Step-by-Step:
01 - Preheat your oven to 400°F. Line a large baking sheet with parchment paper.
02 - In a large bowl, combine cheddar, Monterey Jack, black beans, bell pepper, green onion, cumin, chili powder, smoked paprika, salt, and pepper. Mix well.
03 - Cut each tortilla in half to create 32 semicircles.
04 - Place a tablespoon of the cheese mixture on each semicircle. Fold the straight edge over the filling to form a triangle, pressing gently to seal.
05 - Arrange the quesadilla triangles, points facing inward and slightly overlapping, in a tight ring on the baking sheet to form a blooming flower shape.
06 - Brush the tops with melted butter.
07 - Bake for 18-20 minutes, or until tortillas are golden and cheese is melted.
08 - Slide onto a serving platter. Sprinkle with fresh cilantro. Place salsa, sour cream, and avocado slices (if using) in small bowls in the center of the ring for dipping. Serve with lime wedges.
