Tortilla pinwheels are a quintessentially Midwestern party staple — you couldn’t throw a proper gathering in NE Ohio without a platter of them on the table. The format took off in the early 1990s when flour tortillas became widely available in Midwestern grocery stores, and creative home cooks like Terri Board found endless ways to fill them. Terri’s version is a crowd favorite: cream cheese and sour cream seasoned with dry Ranch dressing mix, studded with chopped onion and finely chopped green olives with pimento, spread over tortillas and finished with a generous sprinkle of shredded cheddar. Rolled tight, chilled, and sliced into one-inch rounds, they’re as pretty as they are irresistible. Make them the night before and they slice even cleaner.
