Salsa and low fat sour cream whisked together works as the dressing for this incredibly delish meatless taco salad. Onions and a couple of tomatoes cook down in a pan, with some soy chorizo, corn, cilantro and red beans. Cumin, smoked paprika, coriander powder, cayenne and a bit of the salsa-sour cream dressing season the goodies in the pan. A bowl of fresh Romaine/butter lettuce is tossed with the remaining dressing, and layered on a corn tostada, with the bean-soy chorizo mixture, topped with fresh cheddar and avocados ??
