Cook the brown rice according to package instructions until tender and fluffy.
In a small bowl, grate the Asian pear and combine with coconut aminos, minced garlic, and grated ginger.
Thinly slice the flank steak against the grain and toss with the marinade, sea salt, and black pepper.
Heat sesame oil in a large skillet or wok over medium-high heat until shimmering.
Add the broccoli florets and sliced carrots to the pan, stir-frying for 3-4 minutes until vibrant and crisp-tender.
Remove vegetables from the pan, then add the beef in a single layer, searing for 1-2 minutes per side until caramelized.
Return the vegetables to the pan, tossing everything together with any remaining marinade for 1 minute.
Serve the beef and vegetables over the cooked brown rice, garnished with sliced green onions and sesame seeds.
