How to Make It
Coat cold grill cooking grate with cooking spray; place on grill over medium-high heat (350° to 400°). Coat corn with cooking spray. Place corn on cooking grate, and grill, covered with grill lid, turning occasionally, 12 to 15 minutes or until lightly browned and done. Remove corn from grill, and cool slightly.
Hold each grilled cob upright on a cutting board, and carefully cut downward, cutting kernels from cob. Discard cobs.
Combine corn kernels, arugula, and next 5 ingredients, tossing to coat. Season to taste with salt and pepper. Serve immediately.
