Is This Recipe Healthy?

  • This salad is very healthy because it’s made using real food ingredients with lots of vegetables and fiber.
  • Instead of using canola oil and soybean oil which is what Costco uses, I used olive oil instead. Olive oil is considered to have a much healthier nutritional profile than either canola oil or soybean oil. Read more about the healthiest cooking oils.
