01 - Carefully remove 8 large cabbage leaves from the head, trimming the thick stem end if needed for easier rolling. Rinse thoroughly and pat dry with paper towels or a clean kitchen cloth.
02 - Place the prepared cabbage leaves on a large serving platter or clean work surface, arranging them in a single layer with the curved side facing down for easy filling.
03 - In a large mixing bowl, combine the sliced mango strips, julienned carrot, thinly sliced bell pepper, julienned cucumber, fresh cilantro leaves, and mint leaves. Toss gently to distribute evenly.
04 - In a separate medium bowl, whisk together the creamy peanut butter, fresh lime juice, soy sauce, maple syrup, grated ginger, minced garlic, and 2 tablespoons of warm water until smooth and well combined. Add additional water 1 tablespoon at a time if a thinner consistency is desired.
05 - Place a generous spoonful of the vegetable-mango mixture onto the center of each cabbage leaf, leaving about 1 inch of space at the edges.
06 - Drizzle the prepared peanut sauce over the filling on each wrap. Sprinkle with the chopped toasted peanuts if using for added crunch and flavor.
07 - Fold the sides of each cabbage leaf inward over the filling, then roll from the stem end toward the leaf tip to form a tight wrap. Serve immediately while the vegetables are crisp.
