- Preheat your oven to 375°F. 
- In a medium bowl, mix together the softened cream cheese, sour cream, cooked sausage, diced peppers, pepperoni, garlic powder, and Italian seasoning. 
- Spread the mixture evenly into a greased pie plate or small baking dish. 
- Layer the pizza sauce over the cream cheese mixture, then generously sprinkle mozzarella cheese on top. 
- Add extra toppings like more pepperoni slices or crumbled sausage, but avoid too many to prevent excessive grease. 
- Bake for 15-20 minutes, until the edges are bubbly and the cheese is perfectly melted. 
- Garnish with Parmesan cheese and red pepper flakes, if desired. 
- Serve warm with toasted baguette slices, pita chips, or crackers.
