Ingredients

Instructions

  1. Step 1: Peel and dice sweet potatoes into 1/2-inch cubes. Boil in salted water for 12-15 minutes until fork-tender, then mash with 1/4 cup reserved cooking water until smooth and creamy.
  2. Step 2: Slice beef strips against the grain into 1/4-inch thick pieces. Heat 2 tbsp avocado oil in a wok over high heat until shimmering. Add beef and stir-fry for 2-3 minutes until browned but not overcooked.
  3. Step 3: Remove beef and set aside. In the same wok, heat remaining 2 tbsp avocado oil. Add minced garlic and grated ginger, sauté for 45 seconds until fragrant and golden.
  4. Step 4: Add kale and 1 tbsp water, stirring constantly until wilted and bright green (about 2 minutes). Return beef to wok, add coconut aminos and 1/2 tsp sea salt. Toss to coat evenly for 1 minute.
  5. Step 5: Serve beef stir-fry over a bed of sweet potato mash, ensuring each portion has equal amounts of both components.
