3 tablespoons buttermilk
1 cup finely ground walnuts
1/2 cup fine, dry breadcrumbs
1 teaspoon salt
2 tablespoons vegetable oil
6 cups torn mixed salad greens
4 cups torn fresh spinach
1 cup (4 ounces) shredded colby-Monterey Jack cheese blend
16 cherry tomatoes, cut in half
Place chicken between 2 sheets of heavy-duty plastic wrap; flatten to 1/4-inch thickness using a meat mallet or rolling pin. Brush buttermilk evenly over chicken.
Combine walnuts, breadcrumbs, and salt in a shallow dish; dredge chicken in mixture.
Pour oil into a large skillet; place over medium-high heat until hot. Add chicken, and cook 3 minutes on each side or until golden. Remove from heat; cool slightly. Cut chicken crosswise into thin slices.
Combine salad greens and spinach, and arrange on each of 4 individual plates. Sprinkle with cheese, and top with tomato halves and chicken. Serve with Buttermilk-Honey Dressing on the side.
