Crab tostadas, red onion & sweetcorn salsa and avocado

Method

1. Make the salsa first. Add everything into a bowl, stir and leave to marinate.
2. In a mixing bowl, add the crab, zest and lime juice, then season with salt and pepper.
3. Heat a large, lightly-oiled, non-stick frying pan. Add the tortillas one at a time and cook for a couple of minutes on each side until golden. Once both sides are done, remove from the heat and sit them inside a bowl to shape into cups. Leave the tortilla in the bowl while you do the next one.
4. Divide the crab filling between the tortilla cups, add a quarter of sliced avocado to each one, sprinkle with a few chilli flakes and serve with the salsa.
