In this tutorial, we learn how to cook a London broil. First, heat up a skillet on medium high and then place your meat onto the skillet. Now, let the meat brown on both sides, and keep cooking, seasoning with salt and pepper as you go. Keep cooking on both sides, making sure not to burn either side of the meat. The outside will be darker on the outside since you are cooking it on a skillet instead of an outside grill. Grab a thermometer and make sure your meat is cooked thoroughly, depending on if you like rare to medium cooked meat.
