01 - Preheat a grill or grill pan over medium-high heat. Grill corn until lightly charred on all sides, about 8–10 minutes. Let cool, then cut kernels off the cob.
02 - In a large mixing bowl, whisk together olive oil, lime juice, lemon juice, Dijon mustard, honey (if using), salt, and pepper.
03 - Add crab meat, grilled corn, cherry tomatoes, avocado, red onion, and herbs to the bowl. Toss gently to coat with dressing.
04 - Arrange arugula or greens on a serving platter or individual plates. Spoon crab and corn mixture on top. Serve immediately, garnished with extra herbs or a squeeze of fresh lime if desired.
