Mushroom and Spinach Frittata

INSTRUCTIONS

Preheat the oven to 350°F (175°C).

In an oven-safe skillet, (Try a Cast Iron Skillet)  heat olive oil or butter over medium heat.

Sauté onions and mushrooms until softened.

Add spinach and cook until wilted.

In a bowl, whisk the eggs with salt and pepper.

Pour the eggs over the sautéed vegetables in the skillet.

Cook on the stovetop for 2-3 minutes until the edges start to set.

Transfer the skillet to the oven and bake for 10-12 minutes, or until the frittata is fully set and slightly golden.

Optional: Sprinkle with shredded cheese before baking for extra flavor.
