Cut the sausage in half length-wise and then slice into 1/2" pieces. They will end up looking like little half moon shapes.
Heat a large pot or Dutch oven over medium-high heat. Then, add olive oil to the pot. Add sausage and sauté until lightly browned. Remove sausage to a bowl, leaving the oil in the pot.
Reduce the heat to medium. Add the leeks. Stir frequently, cooking them for about 10 minutes or until they are very soft. Adjust the heat as necessary so that the leeks do not brown.
Add the potatoes, broth and bay leaf. Bring to a boil. Reduce the heat. Cover the pot and simmer about 10 minutes.
Add corn kernels to the pot and cook until the potatoes are fork tender.
Stir in unsweetened almond milk or your choice of milk. Simmer until heated through. Do not boil.
Ladle into bowls and garnish with Kale chips.
