Heat the olive oil in a large saucepan over medium heat. Add onion, garlic and red pepper. Cook for ~2 minutes, stirring occasionally. Stir in the crumblers and cook for another five minutes, stirring often.
Stir in the remaining ingredients (except cheese) and increase the heat, bringing the mixture to a boil. Place a lid on the pan and bring the heat to low, simmering until the pasta is al dente (about 12-15 minutes)
Once the pasta is al dente, turn off the heat and mix in the cheese. Top with a lid and let sit for 10 minutes. Taste and add more salt and pepper, as desired. Serve!
