Place mango skins in 13x9-inch baking dish, then fill with meat mixture as directed. Cover and refrigerate up to one day. When ready to serve, preheat oven to 400°F. Bake mangos, uncovered, 15 min. or until heated through. Top with sour cream just before serving.
How to Find Mango Seed
Mangos have opposing flat sides. In the palm of your hand, balance the mango on the long side, stem away from you. Place the mango with one flat side resting on the cutting board. Cut the mango lengthwise along the flat side, about 1/4 inch away from the stem, on either side of the seed. Turn mango over and repeat on the other side.
Substitute small papayas, typically called Hawaiian papayas, for the mangos.
