Preheat your oven to 425°F (220°C) for perfect roasting.
Cut the cauliflower into even florets and toss with cornstarch.
Beat the eggs in a bowl and coat each floret in the egg wash.
Roll the egg-coated florets in panko bread crumbs until fully covered.
Arrange the coated florets on a baking sheet, drizzle with sesame oil, and roast for 20-25 minutes.
While roasting, mix orange juice, zest, tamari, rice vinegar, honey, garlic, ginger, and chili flakes.
Once the cauliflower is crispy, toss it in the orange sauce.
Return the sauced cauliflower to the baking sheet, sprinkle with sesame seeds, and bake for an additional 5 minutes.
