Chicken with Feta Sauce

4 (4 ounce) skinless boneless chicken breasts
2 tablespoons balsamic vinegar
1/2 teaspoon ground thyme
2 teaspoons olive oil
1 tablespoon plus 1/2 teaspoon all-purpose flour
1/2 teaspoon oregano
1 cup fat-free milk
1 cup frozen broccoli, carrots, and cauliflower medley, thawed
1/3 cup feta cheese
1 teaspoon fresh lemon juice
2 cups hot cooked rice

On a sheet of wax paper, sprinkle the chicken with the vinegar and thyme.

In a large nonstick skillet, heat the oil. Cook the chicken until browned and cooked through, 4-5 minutes on each side. Transfer to a plate.

Sprinkle the flour and oregano over the pan juices; cook, stirring constantly, 1 minute. Gradually whisk in the milk; cook, whisking constantly, until thick and bubbling, 2-3 minutes. Stir in the vegetables, cheese and lemon juice. Reduce the heat and simmer until the cheese melts, about 2 minutes. Place the rice on a large platter; top with the chicken. Spoon the sauce over the chicken.
