In a large non-stick skillet over medium heat, combine beef and onion; cook, stirring frequently to break up meat for 5 minutes or until browned. Drain fat.
Add tomatoes and macaroni. Bring to a boil. Cover and cook for 10 minutes or until macaroni is tender. (If mixture becomes too thick, add a little water.)
Remove skillet from heat. Stir in cheese, basil, oregano and chilli powder. Cover and allow to sit for 5 minutes or until cheese has melted.
Try using ground caribou or moose in this recipe instead of beef.
Add some frozen corn, peas, or carrots for a vegetable boost.
