Heat the Olive Oil: In a large skillet, warm the olive oil over medium heat.
Sauté Onions: Add the diced onion and sauté for 2-3 minutes until it becomes translucent.
Add Garlic: Stir in the minced garlic and cook for an additional 30 seconds until fragrant.
Combine Ingredients: Pour in the chicken or vegetable broth, then add the pasta, halved cherry tomatoes, Italian seasoning, salt, and pepper.
Bring to a Boil: Increase the heat to bring the mixture to a boil, then reduce it to low and cover the skillet.
Simmer: Allow everything to cook for 10-12 minutes, stirring occasionally, until the pasta is al dente and the liquid is mostly absorbed.
Final Touches: Remove the skillet from the heat, let it sit for a few minutes, and then garnish with fresh basil and optional grated Parmesan cheese before serving!
