Sausage Potato and Swiss Chard Soup

I'm a tad soup obsessed right now so bare with me.  It's cold out.  Enough said.
I loooove swiss chard and wanted to incorporate it into a soup somehow.  I had sausage and potatoes on hand and well, it just made sense.  It kind of reminds me of a Caldo Verde which is a Portuguese soup. 
This is brothy, soothing, savory and you can taste the love.  Yes love.  It tastes like love....because it'll make you feel so dang good.  Just make it and you'll see what I'm saying.  Love.
p.s. the husband inhaled this.  See...Love.

Sausage Potato and Swiss Chard Soup

Serves 4

1 tbsp olive oil
2 Italian sausages, mild or spicy, sliced into 1/2 inch rounds
1/2 sweet onion, finely chopped
2 cloves garlic, finely chopped
2 medium potatoes, cubed bite size
2 tbsp tomato paste
1 bay leaf
1/2 tsp each, dried basil and oregano
3 cups low sodium chicken broth
4 cups water
4 cups swiss chard, chopped
1/2-3/4 tsp salt if necessary (the sausage can be salty so start lightly)
fresh ground pepper

In a large soup pot over medium heat, add the olive oil and brown the sausage until just done.  Remove the sausage and set aside.  Add the onion and garlic, saute for about 5 minutes.  Add the potatoes, tomato paste, bay and dried herbs.  Cook for about 2-3 minutes.  Add the stock and water, bring to a boil, then lower the heat and simmer, uncovered for 15 minutes or until the potato is just tender.  Add the sausage and swiss chard and simmer for another 5 minutes.  Check for seasoning and add salt & pepper if necessary.  Holds well for 2 days in the fridge.
