Prepare the sauce. In a small bowl or deli container, stir together all of the sauce ingredients—the hoisin sauce, ketchup, rice vinegar, sesame oil, garlic, ginger, and hot honey. Set aside or place in the fridge until ready to serve (this step can be done up to 1 week in advance).
Prepare the chicken. Slice each chicken breast in half horizontally, then place them into a resealable plastic bag. Use a meat mallet or rolling pin to beat the chicken to an even ¼'' thickness, then remove the cutlets and set aside.
In a small bowl, mix together the spices—the garlic powder, onion powder, Creole seasoning, smoked paprika, and black pepper. Season the chicken breasts all over with the spice blend. Set aside.
Set up three shallow bowls into an assembly line. Place the flour into one bowl, the beaten eggs into the second bowl, and the panko breadcrumbs into the third bowl, then season each station with salt and pepper (you can also add any remaining seasoning blend from the chicken, if applicable).
With one hand, dredge the chicken breast in the flour, shaking off the excess until a light coating remains. With your other hand, dip the floured chicken into the egg mixture and turn to coat evenly, allowing the excess to drip off. Finally, dredge the chicken in the seasoned breadcrumbs mixture, pressing to coat evenly. Set the breaded chicken onto a plate or cooling rack and repeat with the remaining chicken breasts. (see note)*
Heat the olive oil in a large sauté pan over medium heat. Once hot, add the chicken breasts to the pan and cook for 2 to 3 minutes, until the first side is golden brown. Flip and continue cooking for around 2 to 3 minutes longer, or until done (the internal temperature of the chicken should register to 160℉). Repeat with the remaining chicken breasts, then allow to rest for 5 minutes before slicing into strips.
In the meantime, steam the broccolini for 4-7 minutes, until vibrant green and crisp-tender. Season to taste with salt, butter or olive oil, and a squeeze of lemon juice.
Assemble. Place the prepared rice into a bowl, then top with the chopped chicken and broccolini. Pour or brush over the prepared sauce—if needed, you may need to thin it out with water—then top with sesame seeds and chopped green onions, if desired. Serve warm.
