Bow Tie Beef Skillet

So this is nice and healthy and really yummy. I browned the hamburger and cut up the vegetables beforehand, so it was super quick for dinner.
1 lb. ground beef
2 cups uncooked bow tie pasta
2 medium tomatoes (diced)
1 1/3 cups beef broth
1 can tomato sauce
2 Tblsp Worcestershire sauce
3 medium yellow summer squash, thinly sliced
3/4 c. chopped green pepper
1 c. shredded Parmesan cheese

In a large skillet, brown ground beef then drain juices. Season with salt and pepper. Stir in the pasta, tomatoes, broth, tomato sauce, and Worcestershire sauce. Bring to a boil. Reduce heat, cover and simmer for 10-12 minutes.
Add squash and green pepper. Cook uncovered for 3-4 minutes or until vegetables are tender. Add 1/2 c of the cheese and mix in until melted. Sprinkle remaining cheese on top.
