Beef Chili with Bacon & Black Beans

Fry bacon in large heavy-bottomed nonreactive dutch oven over medium heat, stirring frequently, until browned, about 8 minutes. Pour off all but 2 tablespoons of fat, leaving bacon in pot. Add onions, bell pepper, garlic, chili powder, cumin, coriander, pepper flakes, oregano, and cayenne; cook, stirring occasionally, until vegetables are softened and beginning to brown, about 10 minutes. Increase heat to medium-high and add half the beef; cook, breaking up pieces with wooden spoon, until no longer pink and just beginning to brown, 3 to 4 minutes. Add remaining beef and cook, breaking up pieces with wooden spoon, until no longer pink, 3 to 4 minutes.

Add beans, tomatoes, tomato puree, and 1/2 teaspoon salt; bring to boil, then reduce heat to low and simmer, covered, stirring occasionally, for 1 hour. Remove cover and continue to simmer 1 hour longer, stirring occasionally (if chili begins to stick to bottom of pot, stir in 1/2 cup water and continue to simmer), until beef is tender and chili is dark, rich, and slightly thickened. Adjust seasoning with additional salt. Serve with lime wedges and condiments if desired.
