Start by boiling a large pot of salted water.

In a Dutch oven, heat olive oil over medium heat and add the ground beef. Brown the meat until fully cooked, breaking it apart as it cooks.

Add the chopped onion, bell peppers, and minced garlic to the pot. Cook until the vegetables are softened.

Stir in the crushed tomatoes and beef broth.

Add the Italian seasoning, salt, and pepper.

Let the sauce simmer for about 10 minutes.

While the sauce simmers, cook the pasta according to package instructions until al dente.

Drain the pasta and add it directly to the sauce. Toss everything together until the pasta is evenly coated.
