Pre heat your oven to 200C/400F. Crack the eggs in a bowl, season with salt and pepper, add in the heavy cream and then whisk till nice and frothy. Then add in the shredded mozzarella cheese and mix well. Grease an oven proof pie dish with butter and then pour in the eggs. My pie dish is 7.5″ in size. Then squeeze any water out of the spinach and place at random in the pie dish. Then crumble that feta cheese on top all over and cook in the oven for 15-20 minutes till it’s fully cooked through. Slice and serve. I’d recommend cutting this into 4 parts and that’s 4 servings.
