1. Microwave waffles, one at a time, at high for 15 to 20 seconds or until pliable. Using rolling pin, flatten waffles into 4 3/4-inch circles. Place on baking sheet. Position 1 to 2 pieces of chicken along middle of each waffle. Fold in sides of waffles, overlapping to form cones. Secure with wooden toothpicks. Bake at 400° F about 20 minutes or until crisp.
2. Meanwhile, for sauce, in small bowl stir together mayonnaise, buttermilk, syrup, red pepper, garlic powder and salt. Transfer to serving bowl. Sprinkle with green onions.
