Preheat your oven to 350 degrees Fahrenheit.
Spray a 9x9 square dish with nonstick spray and set aside.
In a large skillet, cook sausage, crumbling, until browned. Drain.
In a large mixing bowl, combine cooked sausage, Velveeta, muenster, sour cream, onion powder, garlic powder, Worcestershire sauce, and dried parsley. Mix to combine.
Pour this mixture into the prepared baking dish, and spread out evenly.
Bake at 350 for 35-40 minutes. The dip will be bubbly and beginning to brown on top.
Serve warm with chips or crackers.
