This taco salad recipe calls for light Catalina dressing, which is a sweet and tangy tomato-based dressing. You can really use any favorite dressing you'd like for your salad. Classic ranch would be great or Bolthouse Farms makes some great Mexican-flavored dressings that are low in calorie. These can be found in the produce department of your grocery store. If you have a Trader Joe's nearby, try their cilantro dressing. It's SO good on this salad and really low in calories and fat too. You could also just use salsa as your dressing to save a few calories. For a homemade dressing option, try this cilantro lime dressing. It's super tasty!
