Preheat your oven to 375°F (190°C) and lightly grease a small oven-safe skillet or ramekin.
Heat the ghee in a skillet over medium heat and sauté the sliced mushrooms until they are golden brown and tender.
Add the baby spinach to the skillet and stir for 1 minute until just wilted, then remove from heat.
In a small bowl, stir together the cottage cheese, sea salt, black pepper, and garlic powder until well combined.
Fold the sautéed mushrooms and spinach into the cottage cheese mixture and spread it evenly into your prepared oven-safe dish.
Use the back of a spoon to create three small wells in the mixture and carefully crack one egg into each well.
Place the dish in the oven and bake for 12 to 15 minutes, or until the egg whites are fully set but the yolks are still slightly runny.
Remove from the oven, garnish with finely chopped fresh chives, and serve immediately while warm.
