==Ingredients==
====Stuff====
For instance
    * 1/2 medium onion, diced (1/2 cup)
    * mushrooms (1 cup)
    * 1 1/2 cups diced cooked sausage-like product

====Base====
    * 2 large eggs
    * 2 large egg whites
    * 1/2 cup all purpose flour
    * 1/2 tsp baking powder
    * 1/4 tsp salt
    * pinch cayenne pepper
    * 1 1/3 cups milk (low fat is fine)
    * 1/4 cup grated Parmesan cheese

==Method==
  - Preheat oven to 400F.
  - Lightly grease a 10-inch quiche/tart pan (or a 9-inch pie plate)
  - Prepare Stuff. For instance, in a medium frying pan, cook onion and mushrooms with a bit of vegetable oil (or cooking spray) over medium-high heat until onions are translucent and tender, and mushrooms are browned. Set aside to cool for a few minutes. Add sausage-like bits.
  - In a large mixing bowl, whisk together eggs, flour, baking powder and salt. Whisk in milk, then stir in Stuff mixture.
  - Pour quiche base into prepared pan. Top with Parmesan cheese.
  - Bake for 25 minutes (30-35 minutes in a pie plate), or until center is set and the outside edge is golden brown.
  - Let set for 5 minutes, then slice and serve.
