Bring a large pot of salted water to a rolling boil. Add your favorite pasta and cook according to package instructions until al dente, typically around 8-10 minutes. Drain and set aside.

In a large skillet over medium heat, pour in oil. Once heated, add chopped onion and minced garlic, sautéing until the onion becomes translucent.

Stir in chopped bell peppers and halved cherry tomatoes, adding half of the Cajun seasoning. Cook until the vegetables start to soften.

Pour in a can of coconut milk and a splash of vegetable broth, mixing in the remaining Cajun seasoning and nutritional yeast if using. Bring to a gentle simmer.

Add the cooked pasta to the skillet, gently tossing it with the sauce. Heat everything together for a few minutes until well-coated.

Remove from heat, transfer to serving bowls, and garnish with freshly chopped parsley and additional nutritional yeast if desired.
