How to Make Prawn Mayonnaise Sandwich (Traditional & Healthy Version)
The Prawn Mayonnaise Sandwich is a beloved fusion dish found in Singapore’s vibrant kopitiam scene and modern cafés alike. Originally inspired by the classic tea-time sandwich, Singaporeans have made it their own by adding local flavors and using the freshest seafood from our markets. This sandwich is a perfect balance of creamy, tangy, and savory—thanks to succulent prawns tossed with a healthier light mayonnaise, crisp cucumber, and fresh lettuce, all tucked between slices of wholemeal bread. In Singapore, you’ll often find this prawn sandwich as a quick lunch option, a light breakfast, or as a grab-and-go snack from hawker stalls and bakeries. Its popularity comes from its rich yet refreshing taste, making it a staple for those seeking a convenient but satisfying meal. The use of local ingredients and the adaptation to suit Singaporean palates showcase the city’s unique blend of tradition and innovation. Whether enjoyed at a bustling kopitiam or packed for a picnic, the Prawn Mayonnaise Sandwich brings together the best of local and fusion flavors in every bite.

Why This Dish is Healthy
This sandwich is a healthy choice because it balances lean protein, whole grains, and fresh vegetables with reduced-calorie condiments. Swapping full-fat mayo for a yogurt blend reduces saturated fat, while wholemeal bread boosts fiber and keeps you fuller for longer. The portion-controlled filling is perfect for weight management and supports heart health, making it suitable for everyday lunches in Singapore’s fast-paced lifestyle.
This Prawn Mayonnaise Sandwich is rich in lean protein from fresh prawns, which are low in fat and high in essential nutrients such as vitamin B12, iodine, and selenium. By using wholemeal bread, you get more dietary fiber, B vitamins, and complex carbohydrates for sustained energy. The inclusion of yogurt and reduced-fat mayonnaise lowers the overall fat and calorie content while keeping the filling creamy. Cucumber and lettuce add vitamins A, C, and potassium, making this sandwich a complete and nourishing meal.
