3/4 cup balsamic vinegar 
1/4 cup tightly packed fresh basil leaves 
2 tablespoons olive oil 
1 garlic clove, minced 
1/2 teaspoon salt 
8 plum tomatoes 
4 boneless skinless chicken breast halves (4 ounces each)
1. For marinade, place first five ingredients in a blender. Cut 4 tomatoes into quarters and add to blender; cover and process until blended. Halve remaining tomatoes for grilling. 
2. In a bowl, combine chicken and 2/3 cup marinade; refrigerate, covered, 1 hour, turning occasionally. Reserve remaining marinade for serving. 
3. Drain chicken, discarding marinade. Place chicken on an oiled grill rack over medium heat. Grill chicken, covered, until a thermometer reads 165°, 4 to 6 minutes per side. Grill tomatoes, covered, over medium heat until lightly browned, 2 to 4 minutes per side. Serve chicken and tomatoes with reserved marinade.
