Ingredients
- 1 lb, thinly sliced against the grain flank steak
- 8 oz, sliced shiitake mushrooms
- 2 tbsp sesame oil
- 1 tbsp, grated fresh ginger
- 3, minced garlic cloves
- 3 tbsp tamari sauce (gluten-free soy sauce)
- 1 tbsp rice vinegar
- 1 tsp erythritol
- 2, thinly sliced green onions
- 1 tbsp toasted sesame seeds
- 1/4 tsp (optional) red pepper flakes
Instructions
- Step 1: Heat 1 tbsp sesame oil in a large wok or skillet over high heat until shimmering. Add 1 lb thinly sliced flank steak and stir-fry for 3-4 minutes until browned but still tender; remove from pan and set aside.
- Step 2: In the same pan, add the remaining 1 tbsp sesame oil. Add 8 oz sliced shiitake mushrooms, 1 tbsp grated fresh ginger, and 3 minced garlic cloves. Stir-fry for 4-5 minutes until mushrooms are golden and fragrant.
- Step 3: Return the beef to the pan and stir in 3 tbsp tamari sauce, 1 tbsp rice vinegar, 1 tsp erythritol, and 1/4 tsp red pepper flakes if using. Cook for another 2 minutes, tossing until the sauce thickens slightly and coats the meat and mushrooms.
