Cook pasta according to package directions. In a large saute pan (that is oven proof) heat the olive oil over medium-high hear. Take the sausage out of the casing, and cook until brown, about 5 minutes.

Add the pepper and onions, cook for a few minutes until they get soft.

Add the red pepper flakes, oregano, and garlic. Cook for another minute. Season with salt and pepper.

Add the tomatoes and simmer for 5 minutes. Add some basil and parsley. I reserve a little for garnish.

Toss in the bowtie pasta.

Add dollops of ricotta cheese.

Layer the mozzarella cheese over the pasta.

Sprinkle with Parmesan cheese.

Put the skillet into a 400 degree oven for 10 minutes or until the cheese is melted and gooey. Garnish with the remaining basil and parsley.
