Wash and cut the cauliflower into bite sized pieces.
In a bowl, combine the water, flour, garlic powder, onion powder, and salt.
Place the panko bread crumbs in a separate bowl.
Dip each piece of cauliflower in the water/flour mixture, tap off the excess, then roll it in the panko bread crumbs. Add more bread crumbs if necessary.
Place the breaded pieces of cauliflower on a parchment paper lined baking sheet in an even layer.
Bake the cauliflower at 425 degrees for 20-30 minutes, flipping at least once, until crispy on all sides.
While the cauliflower is cooking, make a batch of orange sauce
Once the cauliflower is finished cooking, add it to the orange sauce and stir until it is all coated.
Serve your orange cauliflower over white rice and top with optional sesame seeds and green onions.
