1-First, prepare the flank steak by slicing it thinly against the grain to ensure tenderness. Coat the 1 1/2 pounds of thinly sliced flank steak evenly with 1/4 cup of cornstarch before adding it to the slow cooker.

2-Second, in the slow cooker, combine 1 tablespoon toasted sesame oil, 1 teaspoon minced garlic, 1 teaspoon minced ginger, 1/2 cup low sodium soy sauce, 1/3 cup brown sugar, and 1/2 cup water. Stir until the sugar dissolves, creating the base for your savory sauce.

3-Third, add the coated sliced flank steak into the mixture, tossing to coat evenly. For a vegan option, replace steak with tofu or seitan here to keep things adaptable.

4-Fourth, cover and cook on high for 2-3 hours or on low for 4-5 hours, allowing the flavors to meld and the beef to become tender.

5-Fifth, about 30 minutes before serving, stir in 1/2 cup of green onions cut into 1/2 inch pieces for a fresh touch. This final step brings everything together, making the dish ready to pair with steamed rice and vegetables such as broccoli or asparagus.
