Heat olive oil in a large pot over medium-high heat. Add the Italian sausage and cook until browned, breaking it into pieces as it cooks.
Sauté for about 5 minutes until the vegetables begin to soften, then stir in the minced garlic and cook for another minute.
Add the diced tomatoes with juice, chicken broth, Italian seasoning, dried thyme, and dried oregano. Bring the mixture to a boil, then add the pasta.
Lower the heat to a simmer, stirring occasionally for 8-10 minutes until the pasta is al dente.
