Directions:
1. Preheat the grill to medium high. Take a large bowl. Toss the shrimp in it in oil. Season it with salt and pepper. Grill the shrimps for 1 to 2 minutes on each side until it is just cooked through. Be careful not to overcook it as it can turn hard and rubbery. Remove it from the grill.
2. To make Serrano mint sauce, place all the ingredients, except for salt, in a blender and pulse it till it becomes smooth in texture. Season it with salt.
3. Take a plate and arrange lettuce leaves on it. Place around 3 shrimps in each lettuce leaf. Drizzle it with Serrano – mint sauce and chili sauce. Garnish it with a few cilantro leaves. Roll up the lettuce leaves and consume it immediately.
