Instructions

1. Step 1: Slice 12 oz flank steak into 1/4-inch thick strips against the grain. Mince 3 garlic cloves and 1 tbsp fresh ginger.
2. Step 2: Heat 1 tbsp avocado oil in a large skillet over medium-high heat. Add the sliced beef and cook for 2-3 minutes per side until browned but not fully cooked, then remove and set aside.
3. Step 3: Add the remaining 1 tbsp avocado oil to the skillet. Add the minced garlic (3 cloves) and minced ginger (1 tbsp), and stir-fry for 30 seconds until fragrant and golden.
4. Step 4: Add 2 cups broccoli florets, 1 sliced bell pepper, and 1/2 sliced onion. Stir-fry for 4-5 minutes until vegetables are crisp-tender and edges slightly charred.
5. Step 5: Return the beef to the skillet. Add 2 tbsp coconut aminos, 1 tsp sesame oil, 1/2 tsp salt, and 1/4 tsp black pepper. Toss for 2-3 minutes until sauce thickens and coats the beef and vegetables evenly.
