In this tutorial, we learn how to make a hearty spaghetti sauce. First, pour some chopped onions and diced green pepper into a skillet with olive oil. After this, add in a chopped red bell pepper in with the mix. Let this saute for 5-10 minutes covered over medium low heat. You can tell when it's done because the onions will be clear. From here, add in your meat to the pan and then break it up with a spatula. Cook this down and then add in tomato paste after draining the oils from the pan. Let cook and then serve with pasta, enjoy!
