Prepare the satay sauce. Whisk all of the ingredients except for the honey and water together in a small bowl. Taste test before adding the honey - if your peanut butter is quite sweet you may not need it. Add the water one tablespoon at a time until the sauce is the desired thickness. You want it thick but pourable.
Prepare the slaw by mixing all of the ingredients together and pouring around 2/3rds of the satay sauce in. Mix through and set aside.
Heat a glug of olive oil in a saucepan and saute the mushroom and pepper slices on a high heat until the mushrooms are reduced and the peppers are browning. Put them in a bowl and set aside.
In the same pan, heat a little fresh oil and add the halloumi, frying until golden on each side. Add the peppers and mushrooms back into the pan and fry for a moment to refresh them. Add the remaining satay sauce to the pan. Mix through until it's coating all of the slices of halloumi, mushroom and pepper.
Heat your tortillas in the microwave for 30 seconds to soften them and make them pliable.
Roll your wraps! Scoop out the slaw + halloumi and veg filling onto the wrap, then bring the sides in and roll. Eat as one piece or slice in two.
*You can swap this for 1/2 a bag of pre-chopped coleslaw mix + the coriander leaves** I use a low sugar peanut butter which means I like to include the optional honey. If you're using something fairly sugary, taste test before adding the honey.
