Slice the halloumi into 1x3 inch strips ( you could also do 1-inch chunks!)
Grill the halloumi cheese using whichever method you choose! Grill on a grill, grill pan, or panini press. Grill for 2 minutes on each side or 2 minutes total on the panini press.
Assemble the salad by tossing the mixed greens, cucumber, red onion, tomato, and top with the grilled halloumi cheese.
In a small mixing bowl combine mint, garlic, olive oil, pepper, salt, sumac, and lemon juice.
Whisk to create the dressing.
Top the salad with the dressing right before serving and finish with crushed pita chips.
