After this post, I decided to try to bake sausage and peppers and here
is what happened.

I put a layer of Italian sausage, then pricked them. I cut up strips
of fresh onion and bell pepper and baked them in the oven. You can
add garlic.

Then my plan when they were browned was to put about half a large jar
of marinara sauce over them, bake a little more and serve with
rigatoni.

Well they would have been delicious but there is a problem. Italian
sausage has quite a bit of fat and when they are baked, it pools in
the pain.

Either bake them first on a rack and drain or fry them first and then
bake them with the peppers. The bottom line is to get the grease out.
