Combine salt and pepper together in a bowl. Place chicken wings on a baking sheet. Sprinkle with salt and pepper. Toss to coat completely. Bake for 15 minutes. Turn and bake for another 15 minutes or until crispy and cooked through.
During the last 2 minutes of cooking time, heat sesame oil in a skillet over medium heat. Add garlic, onions and jalapeno. Cook just until jalapeno is softened. Reduce heat to low.
Remove chicken wings from oven. Toss in garlic/jalapeno mixture. Transfer to a serving platter. Spoon any left over garlic/jalapeno mixture over the top. Serve.
