Add the bacon to a large saucepan or Dutch oven over medium-high heat. Sauté for about 3 minutes, then add the onion and continue to sauté. Stir often, for another 3-4 minutes or until the onion is translucent.
Add the prepared green beans, along with the fire-roasted tomatoes.
Stir in remaining ingredients and allow to come to a boil. Cover and reduce the heat to maintain a slow simmer. Simmer for 50 minutes, lifting the lid to stir occasionally. Serve and enjoy.
