Sausage and Peppers Baked Pasta

I haven't been feeling well lately, so I have been trying to make easy recipes. This recipe definitely was easy. ALL I had to do was throw everything together. It reminded me of a healthy version of baked ziti, which I love. I will most likely make this again.

Ingredients:
1/2 pound short cut pasta
1 red onion, sliced
1 green bell pepper, diced
1 red bell pepper, diced
1 orange bell peper, diced ( I used 1/2 bag frozen peppers to save on cost.)
1 tsp fennel seeds ( I omitted)
1 tsp dried oregano
salt and pepper
1 15 oz can crushed tomato sauce ( I used homemade sauce)
3 links Italian turkey sausage
1/2 c ricotta cheese
1/2 c shredded mozzarella
1/4 c grated parmesan cheese

If you are eating this right away, preheat broiler. If you are waiting 30min- 1hour, preheat the oven to 300 degrees.
Cook the pasta in a large pot to al dente.
In a large skillet over medium high heat, saute sausage, onions and peppers, season with salt and pepper. Cook for 5 minutes or untl sausage is browned.
Add in spices, tomato sauce and ricotta, toss to mix well.
Add drained pasta to a casserole dish, top with sausage mixture and combine.
Top with cheese.
Broil for 5 minutes until cheese is melted, or bake for 30 minutes to an hour.
