Heat the olive oil in a large pot over medium-high heat and add the shallot, carrots, celery, and onion. Sauté for 5 minutes or until vegetables are softened.
Add the chicken stock to the pot along with the split peas, basil, rosemary, thyme, and salt and pepper to taste. Bring to a boil, reduce the heat to low, cover the pot with a lid, and simmer for 1 hour or until the split peas are tender.
Stir in the pasta of your choice and cook for an additional 10 minutes or until the pasta is al dente.
Serve the Sicilian split pea soup with a sprinkle of fresh herbs, if desired.
