Preheat oven to 400F. Place whisked eggs in a small bowl, set aside. In another bowl place the panko. Dip cauliflower pieces in egg and then roll in panko until fully coated. Place on a baking sheet.
Bake for about 15-20 minutes or until golden brown.
In a sauce pan over medium heat, add all ingredients except the cornstarch + water. Bring to a simmer and stir until completely mixed. In a small bowl, completely dissolve cornstarch in water, then add to the mixture. Stir until sauce reaches a low boil again and cook until sauce thickens (about 2 minutes). Toss cauliflower in sauce until all the pieces are coated. Garnish with sesame seeds and fresh chopped scallions.
