Preheat oven to 425°F and line a rimmed baking sheet with foil.
Cut each potato in half lengthwise, then use the tip of a knife to score cut sides in a ¼" crosshatch pattern. Toss potatoes in olive oil and season with salt, and arrange flesh side-down on prepared baking sheet. Roast for 30 minutes.
Meanwhile, prepare glaze by combining soy sauce, 1 Tbsp honey, and chili garlic sauce in a small bowl.
Remove potatoes from oven and use tongs to flip each half over onto its skin side (try to position potatoes so they are laying flat, using the rim of the baking sheet, if needed, to hold them upright). Spoon chili garlic mixture over flesh and place back in the oven for 15 minutes, or until potatoes are fork-tender.
Meanwhile, combine vinegar, sesame oil, ginger, remaining 1 tsp. honey, sesame seeds, and a pinch of salt in a bowl. Add cilantro and mint; toss to combine.
Arrange roasted sweet potato halves on a serving platter and top with cilantro-mint mixture.
