Here is a VERY easy recipe to start out with. You can use any combination of cheeses & veggies (or meats). I've experimented with many. Just make sure to sweat out your veggies a little so they don't water down your eggs. I make mine with NO crust to save on calories & everything stays the same. The best combination I've made is Bavarian ham & salami for the meat, 3/4 cup of fontina cheese in the quiche and 1/4 cup of parmesan on top. Then, I sprinkle tastefully simple (garlic garlic, about a TBSP) on top. MMM!
