Grilled Chicken with Greek Flavors

Marinate chicken breasts in a mixture of red wine vinaigrette, fresh oregano, and salt for 1 hour. Remove chicken from marinade and cook on a grill, or grill pan, over medium-high heat, turning once, until cooked through, 10 to 12 minutes. Keep warm.

Meanwhile, toss tomatoes, red wine vinaigrette, and salt in a medium bowl. Lower grill temperature to medium. Sear tomatoes, cut sides down, until slightly softened, about 2 minutes. Return tomatoes to bowl and toss with torn fresh oregano.

Slice chicken and transfer to a platter. Spoon tomatoes alongside chicken. Crumble and sprinkle feta cheese plus additional fresh oregano over tomatoes.
