quiche, crustless, with spinach
Preheat oven to 350°.
Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Add ham, onion, and pepper to pan; sauté 4 minutes or until ham is lightly browned.
Sprinkle 1/4 cup shredded Swiss cheese in a 9-inch pie plate coated with cooking spray. Top with ham mixture.
Combine remaining 1/2 cup Swiss cheese, spinach, and next 5 ingredients (through egg whites) in a large bowl; stir with a whisk.
Lightly spoon flour into a dry measuring cup; level with a knife. Combine flour and baking powder in a small bowl, stirring with a whisk. Add flour mixture to egg mixture, stirring with a whisk until blended. Pour egg mixture over ham mixture. Bake at 350F for 45 minutes or until a knife inserted in center of quiche comes out clean.
