Over medium-high heat, brown the sausage slightly. Once the sausage has some color on it, and there is a nice dark fond developing on the bottom of the pot, add the diced onion and sauté until the onion begins to turn translucent, about 3 minutes.
Then add the potatoes. Sauté for another 3 minutes.
Add 2 teaspoons each Better Than Bouillon (garlic and vegetable) to the onion, sausage, potato mix.
Give the whole mixture a good stir and add 4 cups of water. Stir well, scraping up the fond from the bottom and sides of the pot. Bring to a boil, and reduce the heat to a simmer. Simmer for 10 minutes.
Add two cans of drained and rinsed beans. Bring back to a simmer for another 10 minutes.
Stir in the baby kale, cover the pot, and let steam and simmer for 5 minutes.
Turn off the heat, remove the lid, and stir the stew. Ladle into wide shallow bowls and serve.
