Martha Stewart and AllRecipes.com both offer tortilla soup recipes. The Martha Stewart recipe uses black beans, while the recipe from AllRecipes.com requires a slow cooker.
The recipe from Martha Stewart requires garlic, lime juice and chili powder to taste, and other ingredients include tomatoes, chicken broth and corn. Instead of traditional tortillas, the recipe calls for crushed up tortilla chips.
The slow cooker tortilla soup from AllRecipes.com requires 1 pound chicken, which goes into a slow cooker with tomatoes, enchilada sauce, onion, green chiles and garlic. For seasoning, use cumin, chili powder, salt, pepper and bay leaf. The soup base consists of chicken broth. Cook these in the slow cooker for six to eight hours, and then place warm tortilla strips over it before serving.
