These are fast, easy, versatile, and very tasty. Nice with toppings of guacamole, lettuce, salsa, olives, and/or sour cream. Serve with the jicama salad or sliced fresh mango. You can replace the sausage with cooked shredded chicken, beef, or pork. *For vegetarians, replace the sausage with black beans and roasted sweet potato cubes.
