Step by step
Combine all of the dressing ingredients in a small bowl. Cut the halloumi into 9 slices and toss in half of the dressing. Cook on a BBQ, griddle or in a frying pan for 5 minutes, turning halfway through until they’re crisp and browned on the outside.
While the halloumi is cooking put the leaves, celery, spring onion and radishes into a bowl, drizzle with the remaining dressing and mix it through. Divide the salad between the wraps, lay the halloumi slices on top of each and serve immediately.
