Preheat oven to 220ºC, gas mark 7, and cook the pork fillets according to pack instructions.
Meanwhile, mix the soya sauce, mirin and jalapeños in a bowl and set aside.
Remove the pork then warm up the tortillas in the oven for 1 minute. Thinly slice the pork and divide between the wraps. Add the ham, a handful of rainbow salad and a few sprigs of coriander then spoon some jalapeño sauce over everything. Roll up and serve with the remaining sauce.
