Something New for Christmas Breakfast

My mom wanted to try something different this year for Christmas breakfast (what was wrong with the breakfast casserole of my youth??), so I helped her make this Leek, Bacon, and Gruyere Tart. Only it took so long to make, that it was more like a late afternoon snack than a breakfast. Poor planning on our part. I think my mom pulled the recipe from Fine Cooking magazine, but since it was actually pulled completely out, I don't entirely remember. Once we managed to get it cooked, it was actually pretty damn good. I especially loved the thyme in the crust. Nice touch.
