Preheat oven to 180C/160C Fan/ Gas Mark 4.
Dry-fry mince and onion for about 5 minutes until browned.
Add garlic and further fry for 1 minutes, then add tomatoes, puree, oregano, cumin and season.
Slice and deseed the chilli, reserve a few slice for garnish, then finely chop the remainder and add to the mince beef.
Bring to a boil, then cover and simmer for 15 minutes. Spread the mince mixture into the centre of each wrap and roll up and place in the dish.
Top the wraps with the grated cheese and sprinkle the remaining chopped chilli on the top and bake for 10 minutes until golden. Serve with salad or guacamole.
