In a bowl, combine the carrots, golden raisins, mayonnaise, Greek yogurt, lemon juice, and salt and pepper to taste. Stir well.
Divide the carrot mixture evenly between the lettuce leaves, about 1/2 cup for each lettuce wrap. Fold in the short ends of each leaf, then roll up to close. Set the lettuce wraps on a piece of aluminum foil and fold like an envelope to store.
Should be eaten the same day; otherwise, store in the refrigerator for up to 3 days.
