This is the recipe I made (and froze) for my husband and my first night in our apartment after we got married. It comes from Land O'Lakes Recipe Collection Pasta! published in 1992. My mom made this when I was younger, and my sister and I requested it simply for the tomato sauce on pasta. To avoid having to boil the manicotti tubes, simply double the bechamel and tomato sauces. I've made it that way and it works perfectly. Otherwise the noodles tend to stick together closed making filling them impossible. This recipe is completely worth the time and effort!
