Finely dice 1/3 cup of the peppers, using all 3 colors. With the remaining peppers, halve and remove the membrane and seeds.
In a medium mixing bowl, combine diced peppers, turkey bacon, cream cheese, cheddar, onion and seasonings. Mix until well combined using a hand mixer.
Divide the cheeseball into 2 balls, 1 smaller than the other. Place each ball in plastic wrap. Enclose and mold into 2 balls.
On a serving platter, create the "turkey feathers" with a fanned out layer of green leafy lettuce with stacks of the halved peppers on top.
Place the large ball at the base of the board and the smaller ball on top of the larger ball. Fill between the peppers with cucumber slices and around the cheeseball with crackers.
Create the turkey body features with olives for the eyes, candy corn for the beak, a piece of curly lettuce leaf for the gobbler on the smaller ball, and pretzels for the legs on the larger ball.
Add a spreader serving utensil as well as additional dippers or board accents as desired.
