This tasty crustless breakfast quiche, or you could also call it a breakfast broccoli, bacon and feta casserole, is a simple, nutritious, nutrient dense recipe that perfectly balances the taste of the broccoli, bacon, and feta cheese, but adds a freshness of lemon zest and lemon juice. The lemon is a particularly tasty ingredient that adds a refreshing flavor that perfectly completes both the broccoli and the feta cheese. This keto bacon and feta casserole can be served as a warm breakfast or lunch. To make this into a full meal for dinner, you could also add a slice of my Keto Walnut Bread, along with one of these soups: my Keto Thai Pumpkin soup, Roasted Tomato and Red Pepper Soup, Cream of Mushroom Soup, or with a tasty salad such as my Avocado Spinach Strawberry Salad with Balsamic Vinaigrette.
