Heat a small nonstick Dutch oven over medium-heat. Coat pan with cooking spray. Add onion, bell pepper, garlic, and jalapeño to pan; sauté for 2 minutes. Add pork; cook 3 minutes. Add broth and next 6 ingredients (through tomatoes); bring to a boil. Partially cover, reduce heat, and simmer 6 minutes or until pork is done, stirring occasionally. Remove from heat, and stir in cilantro. Serve with avocado.
