Add all of the ingredients to a large bowl except the butter. Mix well with a spoon.
Add the butter to a large nonstick or cast-iron skillet over medium heat. When warm, add ¼ cup of the batter to make each patty, pressing down slightly into a flattened disc about 1 inch thick. Cook for 3 minutes, or until lightly browned, and carefully flip over with a spatula.
Cook for an additional 3-4 minutes and serve warm or let cool on a wire rack to store for later.
(To bake the patties in the oven: Preheat the oven to 400 degrees F and coat a baking pan with nonstick spray. Place the patties on the pan and bake for 12-16 minutes, or until lightly golden brown.)
Serve warm with ketchup, warmed pizza sauce, Ranch, salsa, or guacamole.
