Step 1

Add all the ingredients to a medium sized glass jar. Using a immersion blender, blend until combined. Alternatively, you can use a stand blender for this step. Set dressing aside.

Step 2

Heat a gas or charcoal grill.

Step 3

Marinate the shrimp in a bowl with 1/4 cup of the dressing for 15 minutes.

Step 4

Thread the shrimp onto metal skewers.

Step 5

Lay the shrimp and corn cobs on the hot grill and cook until cooked through (the flesh of the shrimp will turn opaque) and grill marks form, about 2 minutes per side. Rotate the corn a few times during this time. Remove both and set aside.

Step 6

Cut the corn kernels from the cob.

Step 7

To prepare the salad, add the lettuce, black beans, avocado, corn, onion and tomatoes to the bowl with the dressing. Toss to coat well, then transfer to a serving bowl or platter. Top the salad with the shrimp and serve.
