Begin by baking the buns at 325 degrees until browned - about 3 - 4 minutes. Cut the buns in half.
At the same time, form the chicken sausage into patties. Add to a skillet on medium high heat and cook 3 - 4 minutes per side. Remove from heat.
Now begin assembling the sliders. Begin with a piece of mozzarella followed by a dollop of pizza sauce. Next, top with the chicken sausage patty. Repeat the mozzarella slice and pizza sauce again. Place on the top bun and top with another slice of the mozzarella and a piece of the pepperoni. Finish by placing in a 325 degree oven and cook until the cheese melts.
Serve and enjoy!
