1 lb seedless red grapes, stemmed and halved lengthwise (3 cups)
1/4 teaspoon salt
1/8 teaspoon black pepper
2 tablespoons plus 1 teaspoon olive oil
1/2 cup finely chopped pitted green olives (2 1/2 oz)

1/2 teaspoon finely chopped fresh jalapeņo chile
1/2 teaspoon minced garlic
1/2 teaspoon finely grated fresh orange zest
1 tablespoon red wine vinegar

Toss grapes with salt, pepper, and 1 teaspoon oil in a bowl, then roast on a foil-lined baking sheet until shriveled, about 25 minutes. Cool to room temperature on sheet on a rack.
