Add about ¾ cup of water to a skillet along with the garlic and bring to a boil. Add shrimp and cover to poach, about 3 minutes or until pink and opaque. Immediately drain, and rinse in cold water to stop the cooking process. Pat dry and set aside.
Mix together the dressing ingredients (except the cucumber, onion and dill), adjusting to taste however you desire. Stir in the vegetables, herbs, and shrimp.
To serve, place each lettuce quarter on a plate and remove the top few layers to create a ‘bowl’ for the shrimp salad mixture to sit in. Spoon mixture in, letting it spill over the edge of the wedge.
