Preheat oven to 450°F. Mix 2 teaspoons of the Seasoning and panko in shallow dish. Mix egg and water in a separate shallow dish or bowl. Coat chicken with egg mixture, then coat chicken evenly on both sides with panko mixture. Arrange chicken on large shallow foil-lined baking pan sprayed with no stick cooking spray. Discard any remaining egg and panko.
Spray chicken lightly with no stick cooking spray. Bake 20 minutes or until chicken is cooked through.
Remove from oven. Spoon marinara sauce evenly over chicken. Sprinkle with cheese and remaining 1 teaspoon of the Seasoning. Bake 5 minutes longer or until cheese is melted. Serve with cooked spaghetti and Quick Garlic Bread (see below), if desired.
Serving Suggestion: For Quick Garlic Bread, mix 1 tablespoon McCormick® Cheesy Seasoning with 1/2 stick softened butter. Cut 1 loaf Italian bread in half lengthwise and spread with butter mixture. Broil 2 to 3 minutes or until lightly browned.
