Heat canola oil in a large pot over medium heat. Stir in onion and red pepper; cook until onion has softened and turned translucent, about 5 minutes. Add pork sausage; cook and stir until sausage is crumbly and browned, about 10 minutes. Drain and discard any excess fat.

Stir in crushed tomatoes, garlic powder, Italian seasoning, sugar, salt, and pepper. Bring to a simmer over medium-high heat; reduce heat to medium-low, cover, and simmer 20 to 30 minutes until sauce has reached your desired consistency.

Meanwhile, bring a large pot of lightly salted water to a boil over high heat. Add pasta, and cook until al dente, 8 to 10 minutes. Drain; toss with red sauce and Italian cheese blend. Stir until cheese has melted. Season to taste with salt and pepper before serving.
