The veggies were all frozen, except for the stewed tomatoes and pasta sauce (veggies only, meat added at meal preparation time).

The canning overall wasn't the primary source for the nutrition but it was a part of the overall strategy of prepare and store the food, outside of the "food industry".

And trust me, I remember the hard work clearly but I may be looking at the past wistfully wondering how to get my kids to eat more vegetables.
