Preheat a grill or grill pan over medium heat. If you’re using whole potatoes, scrub them clean and dry; slice them into 1/4-inch thick rounds or lengthwise into planks for more surface area.
In a small bowl, whisk together honey, soy sauce, olive oil, minced garlic, salt, and pepper. If you like a little kick, add a pinch of red pepper flakes.
Toss the potato slices with the honey-garlic mixture until they’re evenly coated. Let them marinate just long enough to soak up a bit of the flavor while the grill heats.
Grill the slices for about 3–4 minutes per side, or until grill marks appear and the potatoes are tender when pierced with a fork. Baste once or twice with extra marinade as they cook for extra flavor.
Once cooked, transfer to a platter. If you have extra glaze on the pan, brush it over the hot slices for a shiny finish.
Serve warm as a snack, side, or appetizer. They pair nicely with a yogurt-dill dip or a bright green salad.
