Grilled Lime-Marinated Beef Tostada Salad

With lean grilled beef and market-fresh veggies, this crispy crunchy main-course salad has all the satisfaction of a nacho platter with a fraction of the fat and a BIG boost of nutrients. Using oven-toasted whole wheat flour tortillas as the tostada base is a healthier choice than traditional fried corn tortillas. When cooking the corn and tomatoes, heat just enough to combine and develop their flavours.
