Ingredients

Instructions

  1. Step 1: Slice beef sirloin against the grain into 1/4-inch strips. Pat dry with paper towels to ensure proper searing.
  2. Step 2: Heat sesame oil in a large skillet over medium-high heat until shimmering. Add beef strips in a single layer, searing 2 minutes per side until browned but not cooked through; remove and set aside.
  3. Step 3: Add minced garlic to the skillet and cook 30 seconds until fragrant. Stir in miso paste, rice vinegar, and coconut aminos, then add bok choy stems and cook 2 minutes until slightly softened.
  4. Step 4: Return beef to the skillet, add bok choy leaves, and toss for 1 minute until leaves are wilted and bok choy is crisp-tender.
