Wash the cucumbers, tomatoes, peaches, and arugula. Dry the arugula leaves thoroughly, as any moisture can water down the flavor.
Slice or cube the halloumi, peaches, cucumber, and tomatoes. Finely chop the mint leaves and set them aside.
In a small bowl, stir together the honey and lemon juice. Add the halloumi cubes to this mixture and toss until fully coated. Set aside for a few minutes to let the flavors soak in.
To make the dressing, mix the pomegranate molasses, chili flakes, chopped fresh mint, and a pinch of salt in a separate bowl. Set aside.
Heat a dry skillet over medium-high heat. Add the halloumi cubes (no oil needed) and cook for about 2 minutes on each side until golden and lightly browned all over.
Once the halloumi is cooked, pour the leftover honey and lemon mixture into the bowl with the pomegranate dressing. Stir until well combined.
To assemble the salad, place the arugula, cucumbers, peaches, golden halloumi cubes, and tomatoes in a large bowl.
Drizzle with the dressing and gently toss to coat everything evenly.
