Whisk together stir fry sauce ingredients: ¼ cup coconut aminos, 2 teaspoons sesame oil, 2 teaspoons sriracha, 1 tablespoon rice vinegar, 2 teaspoons minced garlic and 2 teaspoons minced fresh ginger. Set aside for now.
Heat 2 tablespoons oil in a large skillet over medium-high heat. Add ground beef, season with salt and pepper, and cook 6-8 minutes until browned, breaking it up as it cooks. Drain beef in strainer and keep aside for now.
Add ⅓ cup water and broccoli florets to skillet, cover, and steam until bright green and fork tender(about 3 minutes).
Add the beef back to the skillet and pour in the sauce. Stir to coat completely and simmer for 2-3 minutes.
Serve immediately over rice or cauliflower rice and garnish with sesame seeds or green onions.
Notes
Store in an airtight container in the fridge for up to 4 days. Reheat in a skillet or microwave until warmed through.
You can use frozen broccoli, but be sure to thaw it and pat it dry to avoid adding extra moisture to the pan.
