    Trinkets's Note:

    Crustless quiche is a no brainer in our house. We regularly throw together leftover vegies, a little cheese, and eggs fresh from our chickens together, pop into the oven and Voila! Breakfast for everyone! The caramelized onion with spinach and Gruyere is my all-time favorite. I usually use fresh spinach but the frozen box is easy, too.

      Trinkets, I apologise for having had to use zucchini instead of spinach -- our only decent shop had neither fresh nor frozen! I liked your recipe for its simplicity and creaminess!! Didn't change anything else (I used 1 cup cream and 1/2 cup milk). I hope 5 stars show up, because the new format and colours have me confused! This quiche is soft and creamy, and quite delicious. Next time I WILL do it with spinach. Thanks!!

      I made this the other night for dinner and it was fantastic! I serve it with garden salads and nothing else and it was plenty filling. The only change I made was using extra cheese (wanted to use up the rest of the block I had), therefore I had to add 2 extra eggs. I changed nothing else and it came out beautifully! We love quiche in our house and now we have a new recipe for life. Thanks Trinkets!
