Place a large frying pan (one that is about the size of the tortilla) over medium heat. Add the cherry tomatoes, red onion, chicken, dried oregano and spinach and let it cook for 2–3 minutes. Add the sweet chilli sauce and stir through, then flatten out. Season the eggs with salt and pepper, then pour them onto the tomato mix. Add half the grated cheese and cook for 3 minutes.
