When you bring home a whole can of chipotle chiles in adobo sauce, seed the peppers and then puree them with the sauce in a food processor to make a smooth paste. Remove what you need and store the rest in a small plastic freezer bag (push the puree to the bottom of the bag to make a roll) in the freezer. The next time you need some, cut off about 1 inch of the puree for each tablespoon and return the rest to the freezer. The meatloaves can be cooled and wrapped in foil for a make-ahead meal. Freeze for up to 1 month or refrigerate for up to 1 week. Reheat in a 350 degree F oven for 30 minutes if refrigerated or 45 minutes if frozen.
