- In a Dutch oven or stockpot, heat 2 tablespoons oil over medium-high heat. Season beef with salt and pepper; brown in batches, adding oil as needed. Remove with a slotted spoon. Add onion and sweet potatoes to pan. Cook, stirring occasionally, until onion is translucent and light golden brown.
- Meanwhile, puree tomatoes and their juices in a blender or food processor. Place thyme and rosemary on a double thickness of cheesecloth. Gather corners of cloth to enclose herbs; tie securely with string.
- Return beef to pan; add herb bag, tomatoes and broth. Bring to a boil. Reduce heat; simmer, covered, until meat and potatoes are almost tender, about 20 minutes. Add green beans. Cook until meat, potatoes and green beans are tender, about 20 more minutes.
- Add corn, chocolate and coffee, stirring until well blended. Discard herb bag. If desired, season with salt and pepper to taste.
