Put the corn kernels in a large microwave safe bowl (do not add water) and microwave, on high, for 2 minutes. I like to stir the corn at the 1 minute mark. You're looking to very lightly steam the corn, just to take the raw edge off, but not cook it.
Transfer the corn to a fresh bowl and let it cool a bit while you make the dressing. Put all the dressing ingredients into a small food processor and process until smooth and creamy. Scrape down the sides of the bowl as needed to get everything incorporated. Taste to adjust any of the ingredients.
Toss the corn with some of the dressing. Slice the tomatoes in half and add them along with the onions to the bowl. Add more dressing to lightly coat. Serve immediately with a fresh grinding of coarse black pepper, or cover with plastic and chill in the refrigerator. Note: if you plan to make the salad ahead I recommend adding the tomatoes just before serving, as they get mushy in the refrigerator.
Notes
If you don't have a blender you can emulsify the dressing by hand: put everything into a small jar with a tight fitting lid and shake vigorously until the dressing comes together.
