Pat the steak strips and shrimp dry with a paper towel and season evenly with 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 steak strips in a single layer and sear for 2 minutes until browned and caramelized, then remove from the pan and set aside.
Add the shrimp to the same pan and cook for 1-2 minutes per side until they turn pink and opaque, then remove and set aside with the steak.
Toss the broccoli, bell pepper, and snap peas into the pan, adding a tablespoon of water if needed to steam-fry for 3-4 minutes until tender-crisp.
Stir in the minced garlic and grated ginger, cooking for 30 seconds until the aroma is released.
Return the steak and shrimp to the pan, pour in the coconut aminos and toasted sesame oil, and toss everything together for 1 minute to coat in the glaze.
Serve immediately while the vegetables are vibrant and the sauce is bubbling.
