1. Preheat oven to 400 degrees F.
2. Line a large baking sheet with foil, parchment paper, or just spray with non-stick cooking spray.
3. Spread sausage and vegetables evenly on the prepared pan.
4. In a small bowl, mix together the olive oil, garlic cloves, Italian seasoning, paprika, salt, and pepper. Add to the sausage and vegetables and toss to coat it evenly.
5. Spread out the sausage and vegetables as much as you can.
6. Bake for 25-30 minutes, flipping halfway through. Cook until desired cooked/crispiness level. Keep your eye on it for the last 5-10 minutes as some vegetables may possibly cook faster than others.
7. Add more salt and pepper as desired.
8. Optional: Sprinkle parmesan cheese over everything and put it back in the oven for 30 seconds.
9. Keep in the fridge in an airtight container for up to 4 days.
