Regarding salt: I recommend adding salt to taste. The amount you will you will vary based on your personal preference and the broth you are using. The vegetable broth I used here contained salt so I didn't add any additional salt. If you use an unsalted vegetable broth (which I often do) you will find yourself adding 1/2 tsp salt (or to taste).
