If the skillet has dried out, add a drizzle more oil. Then add the onion, bell peppers and garlic. Cook until the vegetables have softened a bit. Stir in 2 1/2 cups water, pasta, cumin, chili powder, oregano, paprika, granulated garlic, granulated onion, and a large pinch of salt and pepper. Bring to a simmer over medium-high heat. Cook, stirring occasionally, until the pasta is al dente and cooking water has thickened, about 12 to 14 minutes.
