- 4 cups cubed fresh pumpkin
 - 1 (10 ounce) potato, peeled and coarsely chopped
 - 4 1/2 ounces fresh spinach, chopped
 - 7 ounces crumbled feta cheese
 - 3/4 cup shredded Cheddar cheese
 - 8 eggs, lightly beaten
 - 1 small red onion, thinly sliced
 
- Preheat oven to 400 degrees F (200 degrees C). Lightly grease a 10-inch square baking dish and line it with parchment paper.
 - Place the pumpkin in a microwave-safe bowl; cover and cook in microwave on full power, stirring halfway through cooking time, until tender, about 5 minutes. Place the potato in a microwave-safe bowl; cover and cook in microwave on full power until tender enough to pierce with a fork, about 4 minutes.
 - Combine the pumpkin and potato in a large bowl. Add the spinach, feta cheese, Cheddar cheese, and eggs; stir. Transfer mixture to prepared dish; top with sliced onion.
 - Bake in preheated oven until firm, about 25 minutes. Allow to rest 5 minutes before serving.
