Bring a pot of salted water to a boil. Once boiling, add the tortellini and cook according to package instructions.
Meanwhile, preheat a large skillet over medium high heat. Drizzle in the oil, and when hot, add in the red pepper and onion powder. Stir to coat with oil and continue to cook, stirring occasionally for 5 minutes. Lightly season with salt and pepper. Add in the sausage mixing to combine, and cook for another 7 minutes.
Add in the garlic and cook for 1 minute. Stir in the wine, and cook stirring occasionally until the alcohol is evaporated, about 3 minutes.
Reduce heat to medium, stir in the cream and sriracha and cook until the sauce starts to thicken a little bit, about 3 minutes. Taste and season with salt & pepper.
Stir in the spinach and cook for 2 minutes allowing the spinach to lightly wilt. Add in the cooked tortellini and cook for a minute or two to warm them through.
