Personally, I like to modify my favorite recipes. It might take a while to get used to the taste of less salt, but eventually you will get used to it. Do youy like to cook for yourself? Do you currently add salt when cookong?

mrs dash flavoring
onion soupm64 oz is 2 boxes unsalted or no salt beef stock
3-4 onions cut in half and thinly sliced 3 tablespoons butter
3 tablespoons flour 1 tsp pepper to taste
melt butter med heat, add all onions, saute , not browned, stir 15 min, add flour and pepper to dissolve, add beef stock , stir, raise heat to high, once boiling reduce to low and simmer 15-20 minutes, yummy, enough for 4-5 days for me, I have 2 pieces of toast and break in mini pcs like croutons to fill me, add thin mozzarella or swiss cheese if allowed after soup is done, great for kidneys, put raw onions on sandwich or salads

stress can harm many parts of the body, relax, do yoga, exercise , pool etc read, visit friends etc
