Recipe by Mirj2338

I'm cutting down on carbs and invented this crustless quiche this morning. I made two versions, one with tuna and one without. You can adapt this recipe using vegetables that you like. It's very creamy and yummy, and I'm pretty proud of it if I do say so myself!

I made this for Sunday brunch yesterday. Followed the directions exactly except I substituted oregano for the za'atar spice mix, as Mirj suggested. I also added a handful of leftover fresh broccoli to the mix. This was very creamy and cheesy as the title suggests! There were only four of us but we didn't have any problems eating the entire dish! Another winner Mirj-keep them coming!
