Step 1: Preheat your oven to 425°F (220°C). Slice the cauliflower into 2-3 steaks, about 1 ½ inches thick.
Step 2: In a mixing bowl, combine Panko bread crumbs, raw sesame seeds, kosher salt, and black pepper. Mix well.
Step 3: In another bowl, beat the egg until fully combined.
Step 4: Brush each cauliflower steak with oil, dip in egg, and then coat with the breadcrumb mixture.
Step 5: Place coated steaks on a baking sheet lined with parchment paper. Bake for 25-30 minutes until golden brown, flipping halfway.
Step 6: In a mixing bowl, whisk together soy sauce, citrus juice, lime juice, rice vinegar, ginger, honey, and chili sauce to make the ponzu sauce.
Step 7: Serve the baked cauliflower with the ponzu sauce drizzled over and garnish with pomegranate seeds and cilantro.
