Let turkey and cheese sit at room temperature for about 15 minutes so everything heats evenly. For an extra Thanksgiving vibe, add a thin layer of stuffing. If your cranberry sauce is runny, drain it slightly to prevent soggy bread. Store cooked paninis up to 2 days refrigerated and reheat in a skillet or press. For make-ahead, assemble and freeze (uncooked) up to 1 month; cook from frozen, adding a few extra minutes.
