Preheat the oven to 180°C (160°C for fan ovens) or Gas Mark 4. Place the wraps on a baking sheet and bake in the oven for 5-8 minutes.
Heat the oil in a large non-stick frying pan and cook the peppers and onion until they are starting to caramelise, set aside on a plate.
Add the filet pieces to the pan and cook until turning light golden brown, return the vegetables to the pan, add the seasoning and cook for a another minute.
Make a quick corn salsa – mix the sweetcorn with the diced onion, avocado and lime juice. Sprinkle with the coriander leaves. Season with black pepper.
Place everything into bowls or plates on the table and enjoy!
