Preheat oven to 400° F. Spray a 9-inch glass pie plate with cooking spray or use a silicon pie plate.

In a 10-inch skillet, cook beef and onion over medium heat. Stir occasionally. Drain. Add salt, garlic powder and Cajun seasoning. Spread in pie plate. Sprinkle with cheese.

In a small bowl stir the Original Bisquick mix, milk, and eggs with a wire wish until blended. Pour into pie plate.

Bake about 20-25 minutes or until a knife inserted into the center comes out clean.

You can add to your slice ketchup, BBQ sauce, bacon or anything else you would normally top your cheeseburger with.
