Preheat the oven to 400º F. Soak the corn in the sink or a bowl filled with cold water for 10 to 15 minutes. Place on a baking sheet with sides and roast for 20 to 25 minutes, until the kernels are tender. Cool to room temperature, then pull off and discard the husks and silks. Cut the kernels off the cob into a large bowl.
Add the mozzarella, avocados, tomatoes, basil, salt and pepper to the bowl with the corn. Drizzle 1⁄2 cup of the vinaigrette over the salad and toss gently. Be careful not to over-mix or mash the avocado. Season with more salt, pepper or vinaigrette to taste. Serve on a bed of the arugula or baby greens.
