Heat a large skillet over medium-high heat.
Add the ground beef to the skillet, breaking it apart with a spatula, and cook until browned and cooked through.
Season the beef with sea salt and black pepper, then remove it from the pan and set aside.
In the same skillet, add the toasted sesame oil, minced garlic, and grated ginger, sautéing for 30 seconds until fragrant.
Add the broccoli florets and shredded carrots to the pan with a splash of water, covering for 2 minutes to steam until tender-crisp.
Return the beef to the skillet and pour in the tamari, tossing everything together to coat evenly.
Serve the beef and vegetable mixture in a bowl, garnished with sliced green onions and toasted sesame seeds.
