This is my absolute favorite fish recipe for its wonderful flavor and ease of preparation. I love Mediterranean food and the mild, tender Roughy is a fantastic compliment to the fresh and vibrant feta, caper and tomato topping. This is a great, healthy recipe that will have you feeling like you just ate in a fancy restaurant. I adapted this recipe from a recipe found at epicurious.com. As usual, substituting or eliminating any ingredients will greatly change the flavor as each ingredient compliments the other.
