- In an oven-safe skillet, heat 1/2 tablespoon coconut oil over medium heat.
- Sauté vegetables for 3 minutes, until the onion is translucent and the mushrooms have softened.
- Remove vegetables from heat and set aside.
- In a medium-sized mixing bowl, whisk eggs.
- Stir vegetables into the eggs.
- Heat 1/2 tablespoon coconut oil in the oven-safe skillet over medium-low heat.
- Pour frittata mixture into the skillet and slow cook for 4–5 minutes.
- Transfer frittata to the oven and cook for 12 minutes, or until the frittata has achieved a spongy firmness to the touch.
