Cut the halloumi cheese into 1/3 inch slices. You don’t want to make them too thin since they will shrink a little in the grill.
Grill the halloumi for about 3-5 minutes on each side. You should see nice grill marks along the sides.
Prepare the salad by washing and cutting your veggies. Cucumbers into small slices and tomatoes in half. Chop your walnuts as well and combine in a salad bowl.
Wash the baby arugula and throw it in the bowl as well.
When the halloumi has grill marks on both sides, arrange it on top of your salad, sprinkle some salt and dress with olive oil and balsamic vinegar.
