Good choices for condiments include diced fresh tomatoes, diced avocado, sliced scallions, chopped red onion, chopped cilantro leaves, sour cream, and shredded Monterey Jack or cheddar cheese. If you are a fan of spicy food, consider using a little more of the red pepper flakes or cayenne--or both. The flavor of the chili improves with age; if possible, make it a day or up to five days in advance and reheat before serving. Leftovers can be frozen for up to a month.
