1. Bring a large pot of water to a boil. Drop the garlic
in the water and season it with
salt. When it boils, add the shrimp and cook for 3 1/2 minutes, until just cooked through.
Drain the shrimp, run under cool water and peel.
2. In a large bowl, combine the shrimp, beans, basil and
onion. Season with salt and
pepper. Sprinkle with vinegar, and fold together. Sprinkle with olive oil and fold again
gently until all the ingredients are well blended and the basil is lightly wilted. Taste and
adjust seasoning. (Note: If you are serving this more than 2 hours later, add vinegar
just before serving, or it will turn the basil black.)
