4 cups Button Mushrooms
1 Red Onion
2 tbsp Olive Oil
6 tbsp Feta Cheese
1 pinch Salt

- Peel and slice a red onion 6 mm slices. Clean button mushrooms; then cut into 6 mm slices. In a sauté pan with olive oil, sweat onions and mushrooms under a medium flame until tender. Remove from heat and place on a dry kitchen towel.
- Preheat the airfryer to 200 degrees. In a mixing bowl, crack 6 eggs and whisk thoroughly and vigorously, adding a pinch of salt. In a 20 cm heat resistant baking dish, coat the inside and bottom with a light coating of pan spray. Pour eggs into the baking dish, then the onion and mushroom mixture and then the cheese.
