Strip steaks can be substituted for the rib eyes, if desired. Mirin can be found in Japanese markets and your supermarket's Japanese foods section. We like to serve the steak and vegetables with Simple Hibachi-Style Fried Rice, Spicy Mayonnaise (Yum-Yum Sauce), White Mustard Sauce, and Sweet Ginger Sauce. If using a nonstick skillet, heat the oil in the skillet over medium-high heat until just smoking before adding the steaks in step 2.
