Heat a large skillet over medium heat. Add the avocado oil and once the oil is shimmering, add the broccoli. Cook the broccoli until it starts to become tender, but still al dente. Remove the broccoli from the pan and set aside.

Next, cook the ground beef in the same pan. Add a little more oil if needed, and cook until it is evenly browned and cooked through. Drain out the excess fat. 

While the beef is cooking, mix all the sauce ingredients together. Add the garlic, coconut aminos, water, ground ginger, coconut sugar, red pepper flakes, sesame oil, and salt to a small bowl and whisk together. 

Add the broccoli back to the pan, and then add in the sauce mixture. Cook for a couple of minutes and bring the sauce to a simmer and then make a slurry to thicken by combining one tablespoon of cornstarch with one tablespoon of water. Whisk with a fork to remove all the clumps, and then pour over the beef and broccoli. Stir to fully combine and bring the mixture to a simmer. The sauce will thicken as it heats. 

Once it has thickened, remove it from the heat and serve immediately. Optional to serve with rice or cauliflower rice and garnish with sesame seeds.
