To prepare wraps, lay out one blanched leaf, stem side toward you. Line the middle of the leaf, left to right, with about ¼ to ½ cup of rice noodles. On top of the rice noodles, pile a few pieces of carrot, red cabbage, and red pepper. Sprinkle with a pinch of green onions and cilantro. Fold the bottom of the collard leaf up over fillings. Fold in the right and left sides of collard leaf and roll toward the top, like making a burrito. Set aside and repeat process with remaining collard green leaves and fillings. Serve with peanut sauce (if desired).
