Instructions:
- Make the salad first, so it will be ready to top with the poached shrimp. The salad is most flavorful when made several hours ahead.
- Cut the kernels from the cob directly into a large salad bowl
- Add remaining vegetables and basil to bowl, but do not toss
- Add lime juice, oil and sprinkle with salt
- Toss very gently, taking care to coat with dressing while keeping tomatoes and avocado pieces intact
- Let sit for at least 15 minutes before serving or cover with plastic wrap and let rest in a cool place for up to 4 hours
