When I had my busy catering business, Cuisine Affaire, in the 1980s and early 90s, these Carrot, Peanut Butter and Raisin Ribbon Sandwiches were a hit at cocktail parties. My sister used to make them by the hundred for us. Best of all, they are vegetarian and suit all ages – so great for a family and lunchboxes – easy to eat and full of goodness. Use any breads you like.
