Beef Steak Bitoque

When the sweet potato has 10-15 minutes to go, place a saucepan (with a lid) over a medium heat with a drizzle of oil. When hot, add your onion and let it sweat for about 3-4 minutes, until softened. Add your sliced spinach and let it wilt for 3-5 minutes (lid on). Once wilted, add your crème fraîche and stir to combine. Season with some salt and pepper. Reheat on a low heat to prevent the crème fraîche from splitting.
