Slice the chicken breast and flank steak into thin, uniform strips across the grain.
Mince the garlic clove and finely grate the fresh ginger.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Add the beef and chicken strips to the pan, seasoning them with sea salt and black pepper.
Sear the proteins for 3-5 minutes until browned and cooked through, then remove from the pan and set aside on a plate.
In the same pan, add the broccoli florets, sliced red bell pepper, and sugar snap peas.
Stir-fry the vegetables for 3-4 minutes until they are tender-crisp and vibrant in color.
Return the cooked meat to the pan and stir in the coconut aminos, toasted sesame oil, minced garlic, and grated ginger.
Toss everything together for 1 minute until the sauce is well-combined and the aromatics are fragrant.
