Add the tamari, bone broth, and sriracha to a small measuring cup or mixing bowl and stir to combine. (If you want it a bit on the spicier side, add some of the reserved kimchi juice as well.) Set aside.
Heat sesame oil in a large Dutch oven or deep-sided skillet over medium-high heat.
Add the onions and kimchi and cook for 1 to 2 minutes until the onions are translucent.
Add the garlic and ginger and continue cooking for another minute or so until fragrant.
Add the shredded chicken and stir to thoroughly coat.
Add the leftover rice, stirring to incorporate.
Once the rice is incorporated, allow it to “fry” undisturbed for a couple of minutes, then stir and repeat. (This only takes a few minutes, but it will give the rice more of a “fried rice” texture.)
Add the tamari, bone broth, and sriracha mixture to the rice and chicken and cook for another couple of minutes while the moisture is absorbed.
Add frozen veggies and edamame, stirring to incorporate.
Serve with garnishes of choice, such as lime wedges, cilantro, and sesame seeds, and enjoy!
