If you're starting with raw meat, cook meat in a large pot (the one you'll use for the pasta), until cooked through.
Add the liquid and pasta to the pot and bring to a simmer over medium high heat (if you're using cooked meat, you can add it now).
Reduce to medium heat and cook, stirring occasionally, for 10-15 minutes until pasta is cooked.
Stir in cheese and extras.
Notes
* See post above for instructions on when to add veggies, and for more details regarding adding types of meats and extras. *Use the formula as a guide and double, triple, quadruple the measurements as needed!
