Begin by bringing water to a boil; drop in rotini spiral pasta and cook for 9 minutes, stirring occasionally. Meanwhile, slice bell peppers, tomatoes, onions, and parsley. Add to a large mixing bowl along with Daiya cheese, stir.
In a separate, small bowl, whisk together dressing ingredients; set aside.
Once pasta is finished cooking, strain noodles and add to veggie mixture. Stir until combined well; the cheese should begin to melt slightly. Slowly stir in dressing and mix until all pasta is covered. Can be served immediately OR divided into meal prep containers for the week ahead.
