  1. When making creamy tuna pasta when you say tomato sauce do you mean ketchup or is it something else
    Thanks cecilia beattie

  2. I just try this recipe but instead of tomato sauce I blender natural tomato with some onion, chicken broth and salt.
    Great result and really easy to do.
    Thanks a lot
