Preheat oven to 375F.

In a large pan, heat olive oil over medium-high heat. Once hot, add onion and cook for 2-3 minutes. Add in sausage and break up using wooden spoon. Continue to cook until no longer pink and fully cooked through.

In a large bowl, add softened cream cheese. Add on sausage and onion mixture, fire roasted tomatoes, pepperoncini, 1 cup mozzarella, and all spices. Mix until well combined.

Pour mixture into a round 9inch dip pan or 9x9 square pan. Top with remaining mozzarella. Bake for 20 minutes and broil for the last 3-4 minutes to get a brown cheesy crisp on top. Let cool 10 minutes before eating.

Serve with crostini or Frito's scoops.
