In a small saucepan, whisk together the water and beef bone broth powder until dissolved, then stir in the brown rice.
Bring the rice to a boil, then cover and reduce heat to low, simmering for 40-45 minutes until the liquid is fully absorbed.
While the rice cooks, heat the toasted sesame oil in a large skillet over medium-high heat.
Add the ground beef, sea salt, and black pepper to the skillet, breaking the meat apart with a wooden spoon until browned and cooked through.
Stir in the minced ginger and garlic, sautéing for 2 minutes until the aromatics are fragrant and softened.
Add the chopped baby bok choy and coconut aminos to the beef mixture, tossing frequently for 3-4 minutes until the greens are tender-crisp.
Fluff the bone-broth-infused rice with a fork and divide it into serving bowls.
Top the rice with the ginger beef and vegetable mixture, finishing with a garnish of thinly sliced green onions.
