Here's a quick and easy recipe that everyone can follow. It's so simple that you really can't mess it up even if you don't know how to cook.
1/4 kilo ground beef
1 medium onion, chopped
4 cloves garlic, chopped
3-4 cups tomato sauce (I used Del Monte Original)
2 tbsps oil
Heat oil in non-stick pan over medium heat. Saute garlic and onions. Throw in the beef and separate clumps. Cook for another 3 minutes and pour in tomato sauce. Season with salt and pepper and keep stirring until it is gently bubbling. Switch to low heat and simmer for 20 minutes. Taste sauce and adjust seasoning.
While the sauce is cooking, boil water in another pot and make sure it's enough to cover the pasta. Add about a teaspoon of salt and oil. Once boiling, add the pasta and simmer for 10 minutes or according to package instructions, until al dente (firm to the bite). Drain and put on a bowl or plate.
Scoop sauce onto pasta and top with grated parmesan.
