Preheat your oven to 400 degrees Fahrenheit and line a large baking sheet with parchment paper.
Toss the halved radishes with olive oil, salt, and pepper in a bowl, then spread them evenly on the prepared baking sheet in a single layer.
Roast the radishes in the preheated oven for 20 minutes, or until they begin to soften and develop a wrinkled, crispy exterior.
While the radishes roast, whisk together the honey, minced garlic, and soy sauce in a small bowl to create the glaze.
Remove the radishes from the oven, drizzle the honey garlic glaze over them, and toss well to ensure every piece is coated.
Return the baking sheet to the oven and roast for an additional 5 to 10 minutes until the glaze is deeply caramelized and bubbly.
Remove from the oven, transfer to a serving dish, and garnish immediately with sesame seeds, fresh chives, and parsley before serving hot.
