1. Season wings with salt (in moderation) and pepper. Heat a gas or charcoal grill to medium hot. Grill wings, turning occasionally, until crisp and golden brown, about 20 minutes.
2. Meanwhile, mix 1 tsp crushed red pepper with the sweet chili sauce in a large bowl. Add the grilled wings and toss to coat. Place on a disposable foil baking sheet and return to the grill for 5 minutes. Turn and continue grilling for 5 minutes. Remove and cover with foil.
3. Peel the mango, cut the flesh from the pit, and slice. Grill mango slices for 3 min., flip, and grill an additional 2 minutes. Chop the peanuts finely.
4. Halve the cucumber lengthwise and remove the seeds. Cut the flesh into 1/4-inch dice and finely chop the shallot. Place in a bowl and add the lime juice, fish sauce, sugar, remaining 1 tsp crushed red pepper and peanuts. Stir until the sugar dissolves.
