Preheat over to 425 degrees F.
Mix the soy sauce, gochujang, honey, sesame oil, sesame seeds, rice vinegar, garlic and ginger together. Pour half over the chicken and stir to combine. Let rest at room temperature as the oven preheats.
Add chicken to a baking sheet and bake for 20 minutes. Then, add a little more gochujang sauce to the chicken, stir, and let BROIL until the sauce thickens and there are crispy bits on the chicken. Make sure to pay attention because you can burn fast (I did about 5 minutes).
Meanwhile, whisk the mayo, gochujang, salt and ketchup together to form the yum yum sauce.
Once done, make Korean-inspired rice bowls, or serve however you choose!
