Slice the peaches into 1/2 inch wedges. Place on a sheet pan with drizzle with olive oil, honey, flakey salt and dry herbs. Broil on high for about 10-12 minutes until the peaches soften. Alternatively, you can grill the peaches on a pan for 2-3 minutes per side. Once the peaches are ready, remove from oven and set aside while you prepare the halloumi.
To fry the halloumi, slice the cheese into 1/2 inch slices. Heat a pan on medium heat with a little oil or cooking spray. Grill the halloumi for about 1-2 minutes on one side, then flip for another minute. I suggest grilling the halloumi right before serving for best texture.
To assemble the sandwich, toast the ciabatta or bread and spread a layer of ricotta on the bottom slice topped with cracked black pepper.
Add the marinated arugula on top followed by the broiled peaches, a drizzle of balsamic vinegar, crushed pistachios, and the fried halloumi.
Top the halloumi with a drizzle of honey and a few leaves of fresh basil.
