    I would suggest that you omit the 2 tsp of salt from the recipe if the canned tomato products you are using are the regular kind rather than the “no salt added “varieties. I would also ask you to include the nutritional information for the recipe as given. ou certainly could not call this recipe healthy with the amount of sodium it contains as given.

      Hi, Lynn. Thanks for your comment. Some people do need to be careful of their sodium intake in order to be at their healthiest. For those individuals, your recommendations could be a good solution. Of course, as individual dietary needs vary, we hope anyone making this or any recipe will be mindful of these considerations as it pertains to their unique situation.
