I LOVE this quiche. It's crustless. The texture is fabulous. You can vary this in many ways by changing the filling ingredients. This one is bacon and Gruyere. I sometimes add green onion and 1/4 c dijon mustard to this recipe. Or I'll go totally different and just add lots of diced and sauteed veggies and omit the bacon and cheese. I like to serve it with a small salad and a cluster of seedless grapes or some melon.
