Place half of the blueberries in a small saucepan with vinegar, thyme and stevia. Bring to a boil, smashing the blueberries with the back of a spoon as it cooks. Remove from heat and set aside.
Mix the chicken, nutmeg, cinnamon and salt in a large bowl.
Press the chicken mix into an eight-inch pizza pan. Cover with plastic wrap and press again or use a rolling pin to make the chicken as flat and even as possible. Remove the plastic wrap.
Bake in a 400 degree F oven for 20 minutes, chicken crust will begin to brown.
Remove the crust from oven and spread blueberry sauce over the pizza and almost to the edge, leaving a 1/2 inch gap with no sauce.
Sprinkle the remaining blueberries over the top of the pizza.
