Cook shrimp in boiling salted water for 2 – 3 minutes until they change color and are tender. Be careful not to overcook them. Remove immediately and rinse under cold water to stop the cooking process. Season with salt and pepper.
Place shrimp on a serving dish.
Combine lime juice with chopped parsley, fresh yellow aji and onion. Mix well and add this to the shrimp. Mix and correct seasoning.
Serve with lettuce leaves, sweet potato slices and cooked kernels.
Garnish with rocoto slices.
