Butternut squash and Italian sausage pasta

1 butternut squash, peeled and chopped up into cubes
1 tray of Italian sausage
1 lb of pasta, I use bowtie
Oil, enough to coat pan
Salt & pepper to taste

Cook pasta.
Remove sausage from casing and fry over medium heat in oil.
Once sausage is cooked through, remove from heat. Reserve oil.
(I scoop out sausage and put it in a bowl. That way I can use same pan.)
Add squash to pan. Add salt and pepper to taste. Cook squash about 20 minutes or until fork tender.
Add sausage and pasta to pan. Toss until mixed.
