I have made this soup now for many years on New Year's Day. I have used chopped kale in place of the spinach and added cooked rice to give it more body.
We love this soup and I make it for New Years and several times through out the year too.I use fresh chopped turnips or collards instead of spinach and I use at least 4 cans of chicken stock instead of beef. I also use 28 oz can of diced tomatoes and 1 lb bag frozen blackeyed peas instead of canned ones.
This soup is absolutely outstanding. It is easy to make and very satisfying. I made it the first time for New Year's, and have made it about a half dozen times since. One of my husband and mine's favorite soups!
