In a large pot, cook onion in olive oil until tender, 3-4 minutes.
While onion is cooking, dice cabbage into ½" pieces. Add cabbage to the pot and cook over medium heat until it starts to soften, about 8 minutes.
While cabbage is cooking prepare other ingredients. Add all ingredients to the pot, bring to a boil and simmer uncovered 15 minutes or until cabbage is tender.
Discard bay leaf, season with salt & pepper to taste and serve.
