Line a baking sheet with parchment paper and set aside. Preheat oven to 400°F.
Cut cauliflower into bite-sizes pieces (about 1 inch).
Put beaten eggs in one bowl and Panko in a second bowl.
Dip cauliflower pieces in egg then roll in Panko until evenly coated; place coated pieces onto the parchment-lined baking sheet.
Bake for about 15-20 minutes or until bites are turning golden brown on the outside.
While cauliflower cooks, prepare honey-garlic sauce by putting honey, garlic, 4 tbsp of water, soy sauce (and Sriracha, if using) into a small pot. Bring to a boil then reduce heat to medium low and simmer for 5 minutes, stirring occasionally.
After 5 minutes, put remaining 2 tbsp of water and cornstarch in a small bowl; stir to blend, then add to sauce in pot. Increase heat and stir as mixture comes to a boil. Cook for 2 minutes, until thickened, then remove from heat.
Put cooked cauliflower in a serving bowl and drizzle sauce over top, tossing with two forks so each bite is coated. Add garnishes if desired and serve hot.
