Place hamburger, mushrooms, garlic and onion in a medium frying pan on medium heat.
Generously season with salt and pepper.
Break up burger and stir occasionally as hamburger browns and vegetables soften. (if hamburger has high fat content, drain excess fat before proceeding)
Heat 3 quarts of water to boiling, add pasta and boil according to package instructions.
Drain cooked pasta and serve, topped with hamburger mix and any other add-ins of choice.
