Preheat oven to 400 degrees Grease a large baking sheet or pizza pan with cooking spray.
In a large mixing bowl, combine all ingredients and mix well.
Put the mixture onto the baking sheet and evenly spread it out, so it is approximately ¼ inch thick. Use an additional baking sheet if there is too much mixture for the pan.
Place in preheated oven and bake for approximately 15-20 minutes, then remove from oven and carefully flip the crust. Replace in oven and bake for an additional 15-20 minutes.
Remove from oven and add toppings of your choosing, then return to the oven for a few minutes to complete if necessary.
