Spray a large pan or pot with olive oil spray. Heat the pan over medium-high heat for 3 minutes.
Add ground beef, onion, garlic and bell peppers in the pan. Cook for 10 minutes or until beef is cooked through and no longer pink.
Add the dry pasta, taco seasoning, tomato paste, broth, and water to the pan. Stir together. Cover the pan and bring to a boil. It should take about 5 minutes to come to a boil.
Once boiling, remove the cover from the pan and reduce the heat to medium. Stir every few minutes for 10-12 minutes or until pasta is cooked and liquid has reduced.
Move the pan off the heat and add in shredded cheese. Stir until combined and melted.
Notes
Storage: keeps in the fridge up to 4 days in an airtight container. Other pasta shapes like rotini, penne, or farfalle can be used in place of shells.
