I did make a couple alterations, first off I beat the egg whites then added the yokes and cream (I don't know if this did anything special but my mom told me to do so). I used fresh spinach about 2 cups finely chopped (probably quite a bit less than 10oz it calls for but maybe not I don't know) I also added a little over a tablespoon on finely chopped walla walla onions. This turned out Amazing everyone loved it including me and I am a picky cook who usually does not eat my own cooking. Yum thanks!!!
This is the first time I made a quiche and it was awesome. My husband and my kids loved it; which surprises me because it has spinach. Very simple preperation and directions; however, I did add a roll out pie crust and opted to crumble bacon on top. Definitely high in fat and calories but oh sooooo good. I would suggest using a little less than 10 oz of spinach.
