- Heat oil in a Dutch oven over medium-high heat. Add onion, bell pepper, garlic, chili powder, cumin, oregano, salt and pepper, and cook, stirring occasionally, until tender, about 5 minutes. Add beans, tomatoes, chipotle to taste, broth and brown sugar. Bring to a boil over high heat, reduce heat, cover, and simmer for 25 minutes.
- Stir in cooked wheat berries and heat through, about 5 minutes more. (If using frozen wheat berries, cook until thoroughly heated.) Remove from the heat. Stir in lime juice. Garnish each bowl with avocado and cilantro.
Tip: Canned chipotle peppers (smoked jalapeños) in adobo sauce add heat and a smoky flavor. Look for the small cans with other Mexican foods in large supermarkets. Once opened, store in an airtight container for up to 2 weeks in the refrigerator or 6 months in the freezer.
