Ingredients

1 tablespoon olive oil, plus more for grates

3 ears corn, husks and silk removed

1 beefsteak tomato (10 ounces), cored, halved, and cut into 1/2-inch pieces

1 orange bell pepper (ribs and seeds removed), cut into 1/2-inch pieces

2 scallions, thinly sliced

1 to 2 tablespoons red-wine vinegar

Coarse salt and ground pepper

Preparation

Heat grill to high; lightly oil grates. Place corn on grill. Cover, and cook, turning occasionally, until tender and slightly charred, 8 to 10 minutes. When cool enough to handle, cut off tip of 1 ear of corn, and stand in a wide bowl (to catch the kernels). With a sharp knife, carefully slice downward. Repeat with remaining corn.

To bowl, add tomato, bell pepper, scallions, vinegar, and oil. Season with salt and pepper; toss to combine.
