Grill the corn, dry, no oil. Just grill it until you begin to get some char marks on the corn. Cut the kernels off of the corn after grilling and place them in a large bowl. Add the bell pepper, onion, cilantro and jalapeño.
PREPARE DRESSING:
In a separate bowl, combine mayonnaise, vinegar, sugar, lime zest and juice. Whisk to combine the dressing ingredients and season to taste with salt and pepper.
Pour the dressing over the vegetables (you may wish to dress the salad lightly and not use all of the dressing, so add a little and then assess if it needs more) and toss gently.
Notes
If preparing this recipe as GLUTEN-FREE, please make sure you are using a brand of mayonnaise that is known to be GF.
Flavors are better if you make this salad 12 to 24 hours ahead of time.
