Chef Laurent Tourondel makes a delicious heirloom tomato and watermelon salad.
Grate ginger on the large holes of a box grater. Wrap ginger in a lint-free cloth and squeeze over a medium bowl to extract juice. You should have about 2 tablespoons.
Whisk ginger juice, along with olive oil and vinegar, until well combined; season with salt and pepper. Add tomatoes, watermelon, chopped basil, and red onion and gently toss until fully coated; season with salt and pepper. Let stand 30 minutes.
Transfer tomatoes and watermelon to a serving bowl. Gently fold in chives, chervil, and parsley; spoon over any remaining marinade. Sprinkle with cheese, and garnish with celery leaves, spring onion, whole basil leaves, avocado, radish. Drizzle with mustard oil; serve immediately.
