Slice the pork loin into thin, bite-sized strips and chop all vegetables into uniform pieces.
In a small bowl, whisk together the chicken bone broth, coconut aminos, toasted sesame oil, and arrowroot powder to create a smooth sauce slurry.
Heat the avocado oil in a large wok or deep skillet over medium-high heat until it begins to shimmer.
Add the pork strips to the pan, seasoning with sea salt and black pepper, and sear until browned and fully cooked through.
Remove the cooked pork from the pan and set it aside on a clean plate.
Add the onion, celery, and mushrooms to the hot pan, sautéing for 3-4 minutes until the vegetables begin to soften and brown slightly.
Stir in the minced garlic and grated ginger, cooking for about 30 seconds until the aroma is released.
Toss in the bok choy and bean sprouts, stirring for 1-2 minutes until the greens are vibrant and slightly wilted.
Return the pork to the pan, pour the sauce mixture over the top, and stir constantly for 1 minute until the sauce thickens into a glossy glaze.
