SPINACH AND CHEESE STRATA - Smitten Kitchen

The fragrance of this dish made my house smile. I'm not kidding. Heavenly. This is a great recipe for brunch or special occasion breakfast.

Leftovers should be reheated in the oven, not the microwave. You want to crisp it up not just make it hot. Also, the recipe says 8 servings but since it is so rich we got around 10 servings. Enjoy.
