If you like a little heat, this spicy Mongolian beef recipe is for you. Using your Thermomix, you can easily create a deliciously spicy sauce by combining soy sauce, chili paste, ginger, and garlic. The beef is then cooked in this flavorful sauce until it's tender and infused with all the spicy goodness. Serve it over a bed of steamed rice and garnish with green onions for an extra kick.
