After spending a lifetime turning up my nose at Brussels sprouts (and all of the cruciferous vegetables), I'm kinda-sorta falling in like with them. It's not yet love, but it's definitely like. I've figured out that roasting, or shredding, or marinating Brussels sprouts brings out the natural sweetness I never knew they had. In this quiche, the sprouts hang out with bacon and cheese, creating a trifecta of textures and flavors that's irresistible. Served at room temperature, quiche makes a lovely light supper main dish, with a green salad on the side, and a glass of something bubbly to wash it all down. For a vegetarian version, simply leave out the bacon. For a gluten-free version, bake it without the crust.
