In a large skillet, heat the oil, 1 turn of the pan, over medium-high heat. Add the bell pepper, jalapenos, red onion and garlic and cook, stirring, until tender, 6 to 8 minutes. Stir in the black beans, cumin and coriander; season with salt and pepper.
In a small bowl, combine the tomatoes, brown sugar and Worcestershire sauce. Add to the black beans and simmer for a few minutes. Stir in the lime juice. Serve the Sloppy Veg-Head Joe on the rolls. Top with the pickles and cilantro.
