Spinach and Feta Quiche with Sweet Potato Crust

Ingredients:

• Avocado oil for coating the pan and sweet potatoes
• 2 medium sweet potatoes, peeled and cut into 1/8-inch-thick slices 
• 1 teaspoon avocado oil, for sautéing the onion
• 1/2 cup sliced red onion 
• 1 (5-oz.) bag fresh baby spinach 
• 1/2 cup whole milk* (See notes for a dairy-free version)
• 1/4 teaspoon kosher salt 
• 1/4 teaspoon freshly ground black pepper 
• 1/4 teaspoon crushed red pepper 
• 4 large eggs 
• 2 large egg whites 
• 1.5 ounces feta cheese, crumbled (about 1/3 cup)* (see notes for a dairy-free version) or if you’re looking for something easy and plant-based try this vegan feta cheese mix

Directions:

1. Preheat oven to 350°F.
2. Grease a 9-inch pie plate with avocado oil.
3. Layer the sweet potatoes slices in slightly overlapping circles on the bottom and sides of the plate.
4. You might need to cut the slices in half to fit them around the sides.
5. Brush the sweet potatoes with avocado oil. 
6. Bake the pie plate in the preheated oven for 20 minutes or until the sweet potatoes are slightly tender.
7. Place the pan on a wire rack to cool. 
8. Increase oven temperature to 375°F.
9. Place a large nonstick skillet over medium heat.
10. Add a teaspoon of avocado oil to the skillet and sauté the onion slices for three minutes.
11. Add spinach to the pan, and sauté for three more minutes.
12. Remove the skillet from the heat, and allow to cool.
13. Combine the milk, eggs, egg whites, salt, black pepper, and red pepper in a medium bowl; combine with a whisk.
14. Arrange the spinach mixture into the cooled sweet potato crust.
15. Pour the egg mixture over the spinach.
16. Sprinkle feta over the filling. 
17. Bake the quiche at 375°F for 35 minutes or until the egg mixture is set.
18. Let the quiche stand for five minutes and serve.

Notes:

For a dairy-free version, swap out regular milk for unsweetened almond milk. Feta cheese has a tangy flavor, and if you’re short on time, you could either use a store-bought vegan feta cheese mix or substitute with kalamata olives to keep that briny flavor. Alternatively, you can make your own vegan feta cheese. This is an easy recipe but it will take some time.
