Ziti With Sausage, Onions, and Fennel Recipe

Directions:

1. Trim fennel, reserving fronds and bulb. Cut fennel bulb in half lengthwise; cut each bulb half lengthwise into (1/4-inch-thick) slices. Cut bulb slices into 2-inch-long pieces. Chop fennel fronds to measure 1/3 cup.
2. Bring 6 quarts water and 2 teaspoons of salt to a boil in a large stockpot. Stir in pasta; partially cover, and return to a boil, stirring frequently.
3. Cook 8 minutes or until the pasta is almost al dente, stirring occasionally. Drain pasta in a colander over a bowl, reserving 2 cups cooking water.
4. While pasta cooks, heat oil in a large Dutch oven over medium-high heat. Remove sausage from casings.
5. Add sausage to Dutch oven; cook 2 minutes or until lightly browned, stirring to crumble. Push sausage to one side of pan.
6. Add onion to open space in pan; cook 1 minute or until onion begins to soften. Stir onion into sausage.
7. Push onion mixture to one side of the pan. Add fennel bulb to open space in pan; cook 1 minute or until fennel begins to soften.
