Preparation
Remove the meat from the lobster shell, cut it into ½-inch pieces, and place them in a large mixing bowl. Add the onion, tomatoes, celery, garlic, olive oil, basil, mint, and the lemon juice, to the bowl; toss. Add the salt and pepper, allowing it to stand for 10 minutes. Combine the arugula with the lobster; toss to coat; sprinkle it with the lemon zest; and serve.
