Slice the pork tenderloin into very thin, bite-sized strips and season them evenly with the sea salt and black pepper.
Heat the avocado oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the pork strips in a single layer and sear without moving for 2 minutes, then toss and cook for another 2 minutes until the edges are golden and crispy.
Add the minced garlic and grated fresh ginger to the skillet, sautéing for about 60 seconds until the aromatics are fragrant.
Toss in the broccoli florets, sliced red bell pepper, and sugar snap peas, stir-frying for 4 to 5 minutes until the vegetables are tender-crisp.
Pour the coconut aminos and toasted sesame oil over the mixture, tossing everything together for 1 minute to glaze the pork and vegetables.
Remove the skillet from the heat and garnish the stir-fry with thinly sliced green onions and sesame seeds before serving hot.
