1. In a small bowl, make the dressing by whisking the mayo, vinegar, and white rub together. Set aside.
2. In a large bowl, combine the corn, onions, chilies, and tomatoes. Add the dressing and stir to combine. Refrigerate for an hour or 2 to allow the flavors to develop. Served chilled.
Notes:
Use fresh corn: Cut the kernels off about 3 medium sized ears of corn and use in place of the canned.
