In a large skillet, saute the bacon, red pepper and onion until bacon is crisp and vegetables are tender; drain. Cool slightly.
In a large bowl, combine the turkey, bacon mixture, 1 cup cheese, salt and pepper. Place 1/2 cup turkey mixture down the center of each tortilla. Roll up and place seam side down in a greased 13-in. x 9-in. baking dish. In a small bowl, combine Alfredo sauce and milk; pour over top.
Cover and bake at 350Â° for 25 minutes. Uncover; sprinkle with remaining cheese. Bake 5-10 minutes longer or until cheese is melted. Garnish with lettuce and tomatoes.
