Preheat oven to 400* F.
Line a large sheet pan with tin foil.
Chop all the vegetables and cut the sausage and add to the sheet pan.
Drizzle with the olive oil and toss to evenly cover all vegetables and sausage. Sprinkle with spices and herbs and toss again. Spread into an even layer on the sheet pan.
Bake for 10 minutes in preheated oven and then toss everything and return to oven for an additional 10 minutes, or until vegetables are tender and sausage is browned.
Remove from oven and sprinkle with parmesan cheese, if desired.
Serve as is, or over rice, if desired.
