Tomato-Herb Marinated Flank Steak Recipe

In this recipe, we make a dual-purpose sauce from garden-fresh tomatoes, shallot, marjoram and rosemary. We use half the sauce to marinate the steak and use the other half as a basting sauce. Pasture-raised, grass-fed beef is gentler on the environment, free from growth-promoting hormones and typically lower in fat and calories than grain-fed beef. Marinating grass-fed beef for a full day helps make it tender. Look for it at natural-foods markets or find it online.
