Corn, radish, tomato and tortilla chip salad

1. Soak the scallions in cold water for at least 20 minutes to crisp them up. Drain and pat dry with a clean dish towel.

2. While the scallions are soaking, prep the tomatoes and corn: First, slice the tomatoes into medium wedges. Sprinkle them with 1/4 teaspoon of the salt and let them sit for at least 10 minutes to bring out their flavor.

3. Run cold water all over the corn. Microwave on HIGH until the corn is steaming hot, 6 to 8 minutes. When they are cool enough to handle, use a sharp knife to cut crosswise through the husk and cob an inch or two from the wide/stem end (opposite from the end with the tassel of silk). Hold the silk end, then push the corn cob out the other end. Discard any stray silks. Cut each cob in half, then stand each half upright and cut off the kernels. (You should have 2 to 3 cups.)

4. In a medium bowl, whisk together the vinegar, oil, remaining 1/4 teaspoon of the salt and the pepper. Add the tomatoes and their juices, corn kernels, radishes and half the scallions, and gently toss. Taste, and add more salt and pepper if needed (keeping in mind that the tortilla chips are also salty).

5. Arrange the vegetables on a large platter. Sprinkle the tortilla chips and remaining scallions on the salad, and serve.
