In a small bowl, use an electric mixer to combine the cream cheese, sour cream, garlic powder, and oregano. Spread the cream cheese mixture into a 9-inch pie plate. Spread pizza sauce evenly over the cream cheese mixture. Arrange the pepperoni, onion and green bell pepper over the sauce.
Bake for 10 minutes. Remove from oven and sprinkle cheese on top. Return to oven and bake until cheese is melted and bubbly.
Serve with sturdy tortilla or corn chips.
Notes
Add black olives if you'd like.
This is great served with Fritos Scoops (dip-worthy corn chips).
