This salad is a healthy and delicious way to enjoy flank steak. The steak is grilled to perfection and sliced thin, then served over a bed of mixed greens. The balsamic vinaigrette is made with olive oil, balsamic vinegar, and Dijon mustard, and adds a tangy and sweet flavor to the salad. Top with crumbled blue cheese and toasted walnuts for a satisfying and flavorful meal.
