Orange Roughy

1 tablespoon butter
1 tablespoon all-purpose flour
1/4 cup chicken broth
1 tablespoon chopped fresh chives
juice of 3 lemons
1/4 teaspoon dried basil
1/4 teaspoon dried thyme
4 (4 ounce) orange roughy fillets
1/4 teaspoon salt
1/8 teaspoon black pepper
1-1/2 tomatoes, peeled and sliced

Preheat oven to 300 degrees F (150 degrees C). Lightly grease a medium baking dish.
Melt butter in a medium saucepan over medium heat, and stir in flour until smooth. Gradually stir in chicken broth and lemon juice. Cook, stirring constantly, until bubbly. Mix in chives, basil, and thyme. Remove from heat, and set aside.

In the prepared baking dish, arrange the orange roughy fillets in a single layer. Season with salt and pepper. Arrange tomato slices over the fish. Cover with the broth mixture.

Bake 30 to 40 minutes in the preheated oven, until fish is easily flaked with a fork.
