For the filling, melt butter over medium heat in a large saucepan. Stir in flour, ¼ teaspoon (0.25 mL) salt, and pepper; cook 1 minute. Slowly stir in milk and cook over low heat, stirring constantly, until sauce thickens, about 5 minutes. Stir in ricotta and set aside.

Step 3

In large skillet, heat oil over medium heat. Add garlic and cook 30 seconds. Add spinach, chicken, 1 cup (250 mL) mozzarella, and sundried tomatoes. Stir in thickened ricotta cheese sauce.

Step 4

Using a teaspoon, stuff manicotti with chicken and cheese mixture and arrange in the greased dish. Top manicotti with tomato sauce and extra cheese. Cover with aluminum foil and bake 1 hour or until manicotti is tender. Uncover, and divide manicotti between plates. Serve with salad.
