Preheat your oven to 350℉ (180℃)
Grease a 9 inch (22 cm) baking dish
Place a skillet on medium-low and heat the oil. Add the onion, cook a few minutes, then add the garlic and cook for a further minute. Now add the spinach, pepper and salt. Cook until the spinach has wilted, about 1-2 minutes.
2 tsp olive oil, 1 small spring (green) onion, 3 cloves garlic, 5 oz baby spinach (small bunch), 1/4 tsp tsp black pepper, 1/4 tsp sea salt
Transfer the mix into your baking dish, spread evenly to cover the bottom.
In a large bowl, whisk the eggs together, add the crumbled feta cheese and fresh herbs.
8 large eggs, 3/4 cup goat or cow feta cheese, 1/2 cup mix of fresh herbs
Pour the egg mixture evenly over the spinach and onion layer.
Bake until cooked evenly and it is just starting to brown a little. It takes normally between 20 - 30 minutes. I like to turn the dish around 180 degrees halfway through.
Remove from the oven when cooked and leave to cool for 5 minutes. Slice into squares or triangles and serve warm.
