Hi Food52ers, My mother is on a very, very salt restricted diet. (She's 93 with congestive heart disease) Several of her favorite dishes use pancetta or pork sausage and without them, they sort of lack. (For instance the great Rancho Gordo recipe for shrimp on top of beans, sausage and arugula - it's sad without sausage) What can I sub in to give the same richness and depth of flavor but without any added salt? Happily she does not have to watch her cholesterol, and she is not a vegetarian. Thanks so much!!
