This past winter I really haven't been into soup but now that we're deep in spring, all I seem to want is comforting soups. We've had two different soups on repeat in our food rotation; a dairy free tomato bisque and split pea soup. Up until recently, my attempts at split pea always turned out rather bland - but I've finally worked away at the recipe to get what I want. My theory is that I was missing a very key ingredient: bacon. And not just added bacon to the final soup, but cooking it in the same pot that you're soup will spend two hours simmering away in.
For a vegan version of this soup, you could easily skip the bacon all together and just cook the vegetables in 2 tablespoons of your favorite cooking oil. Adding some slices of cooked shiitake mushrooms would help pump up the flavor in somewhat similar way to the bacon.
