Preheat oven to 375°F.
In a medium sized bowl, combine the softened cream cheese, sour cream, cooked sausage crumbles, diced peppers, pepperoni, garlic and Italian seasoning until combined.
Spread the mixture into a greased pie plate (or small rectangle pan).
Spread the pizza sauce over the cream cheese mixture and then sprinkle the cheese on top.
Top with additional pepperoni slices*, crumbled sausage, or whatever pizza toppings you desire! (*Don't get too wild on the pepperoni slices....too many will make the top look a bit greasy)
Bake for 15-20 minutes or until the outer edges are bubbly.
Top with grated Parmesan cheese and red pepper flakes, if desired.
Serve warm with the toasted baguette slices, pita chips or crackers. Yum!
