Ingredients

1 teaspoon finely chopped fresh oregano

1 teaspoon red wine vinegar

3 tablespoons extra-virgin olive oil

1 whole boneless, skinless chicken breast, (about 12 ounces), split and pounded to 1/2 inch thick

1 tablespoon minced garlic

1 cup drained jarred or canned white beans, (reserve 1/4 cup liquid)

1 teaspoon finely chopped fresh rosemary

3/4 teaspoon coarse salt

Freshly ground pepper

Vegetable oil, cooking spray

8 slices multigrain bread

4 small radishes, thinly sliced

1 cup thinly sliced escarole

Preparation

Whisk together oregano, vinegar, and 1 tablespoon oil. Brush marinade onto both sides of chicken. Transfer chicken to a nonreactive dish; cover, and refrigerate at least 2 hours or overnight.

Put remaining 2 tablespoons oil and the garlic into a large skillet. Cook over medium heat, stirring occasionally, until garlic has softened, about 2 minutes. Add beans and reserved liquid, and rosemary. Cook, mashing beans with the back of a wooden spoon, 5 minutes. Add 1/4 teaspoon salt; season with pepper. Transfer to a small bowl. Cover, and set aside

Heat a large grill pan over medium-high heat. Coat with cooking spray. Add chicken. Grill, turning once, until cooked through, 3 to 4 minutes per side. Season with remaining 1/2 teaspoon salt. Transfer to a plate; let cool slightly. Cut chicken into 1/4-inch-thick slices; set aside.

Toast bread. Spread each slice with white-bean spread, dividing evenly. Top 4 slices with the chicken, radishes, and escarole, and then the remaining bread.
