Herbed Salsa with Grilled Chicken

To prepare salsa: Place 1 cup tomatoes in a food processor with chives, cilantro (or parsley), oregano, vinegar, salt, pepper and hot sauce. Process until the mixture is coarsely pureed. Add bell pepper and pulse 4 or 5 times to incorporate. Transfer to a nonreactive bowl (see Tips); stir in corn and the remaining 1/2 cup tomatoes. Taste and add more vinegar, salt, pepper and/or hot sauce, if desired.

To prepare chicken: Cut each chicken breast in half on the diagonal to make 4 roughly equal portions. Combine 1/4 cup of the salsa, 2 tablespoons liquid drained from the salsa, 1 1/2 tablespoons oil, chili powder and garlic in a nonreactive medium shallow bowl or sealable gallon-size plastic bag. Add the chicken pieces and stir or shake until well coated. Cover and marinate in the refrigerator for at least 2 hours or up to 1 day. Cover and refrigerate the remaining salsa.

Preheat grill to medium-high or position a rack in the upper third of the oven and preheat the broiler.

Thoroughly shake off the marinade from the chicken pieces and pat dry with paper towels. Brush on both sides with the remaining 1 tablespoon oil. (Discard the marinade.) If broiling, place on a well-oiled broiler pan or wire rack set on a large baking sheet. Grill or broil, turning once, until an instant-read thermometer inserted into the thickest part registers 165 degrees F, 10 to 14 minutes. Serve the chicken with the reserved salsa.
