How Low is your recommendation? 1500mg per day? The raw-er the food the less sodium. Pretty simple.
I have a few lower sodium recipes that I like to cook. One is simply Hamburger meat, brown 1/2 pound of it in a skillet with a small chopped onion (about 1/2 -3/4 cup) and drain it. Put it back in the skillet and add to it a can of NO SALT ADDED diced tomatoes, a cup of high fiber elbow pasta, a cup of water and some seasonings of the Italian variety. (basil, Rosemary, Oregano, etc) Bring this up to a bubble, Lower the temp and let simmer 15 minutes or until the pasta is soft and cooked the way you like it. I like to add a lot of cracked pepper and those red pepper flakes like you get at the pizza restaurants. This serves about 4 people. If you want to raise the fiber even more add some chick peas or white beans. (try to get the dried kind and plump them and cook them yourself without salt, the canned varieties are salt demons.)
This recipe was and is a very common dinner in our house. It is low budget and easy enough to do when you don't have any energy left. Plus it only uses a half pound of meat to serve 4 people! You can also do it with Mexican seasonings, or really whatever you like!
I also make this recipe, except I use veggie crumbles (made be Morningstar it is a non meat substitute) I also add garlic.
