Look at the date on the label. Pick meat that looks very red. Avoid meats that appear maroon or brown or ones that have a lot of blood. They will add flavor to the meat. Also, consider using a red wine.
Herbs can also add a lot of flavor.
Sear the meat by using a nonstick pan or hot grill. This will lock in the flavor and moisture. If you will be roasting the meat, then sear it in the oven at a low temperature to keep the moisture locked in. When searing on the stove, use a high temperature. These methods will help you create a healthy steak.
