1/4 c. best quality olive oil
6 Italian sausages (about 1 1/2 lb.), cut into 1/4" thick slices
1/2 tsp. hot red chili pepper (flakes)
3/4 c. finely chopped fresh parsley, plus 2 tbsp. for garnish
Salt
Lots of freshly ground black pepper
Half & half to desired consistency
Grated Parmesan cheese

Heat oil in large heavy skillet. Add sausages and saute until cooked through, about 5 minutes. Add red pepper flakes, parsley, salt and pepper; cook another 2 minutes. Toss with hot pasta in serving bowl and garnish with parsley. Serve with Parmesan.

I make it as above but also make it with half & half. Simmer until desired consistency. Add half & half if needed.
