"You can use many types of beef, including ground beef, sirloin, flank steak, tenderloin trimmings -- or change this recipe to include other meats such as ground pork, ground turkey, chicken. If you want to go vegetarian, use very firm tofu, cut into cubes. The dish includes cooked rice - please feel free to use whatever rice you want - brown rice, jasmine rice, short grained rice. In a pinch, use basmati. Typical Korean style rice is short-grained. At the market, just look for "short-grained" or sushi rice. Different rice has different cooking times and rice:water ratios, so read the package directions carefully...."
