This is my version adapted from Cooking Light and so, so very good!!! For whatever reason, I don't really like cooking with potatoes or adding a lot of unnecessary starch to my meals thus prompting me to immediately remove the potatoes from the original recipe. Also, my BF doesn't like mushrooms so I leave them out. Instead I use fresh spinach and corn from the cob which makes for a really terrific flavor combination. This recipe makes a lot of quiche so depending on what you choose to cook it in, you may need to adjust cooking time. Also, make sure you drain the veggies after you saute them since the mixture cannot stand any extra liquid or it won't set. Allow to cool for at least 20-30 minutes before serving.
