Have it for lunch - you could omit the pitta chips (or use 1/2 the amount listed) to reduce the cals.

You could prep the chicken and halloumi in advance, just be sure to keep the salad separate so it doesn't go soggy. Store in the fridge for up to 3 days. Ensure the food is completely cool before storing in an airtight container.

If you don't like dill style sauces, you can use tzatziki or even a dollop of hummus.
