Slice the pork tenderloin into thin, bite-sized strips and place them in a bowl.
Toss the pork with arrowroot starch, sea salt, and black pepper until evenly coated.
In a small ramekin, whisk together the honey, tamari, minced garlic, and grated ginger to create the glaze.
Heat the sesame oil in a large skillet or wok over medium-high heat until shimmering.
Add the pork strips in a single layer and sear for 3-4 minutes, turning once, until golden and crispy.
Remove the pork from the skillet and set aside on a plate.
Add the broccoli florets and sliced red bell pepper to the same skillet, stir-frying for 4-5 minutes until tender-crisp.
Return the crispy pork to the skillet and pour the honey-garlic glaze over the mixture, tossing for 1 minute until the sauce is thick and glossy.
