A big pan with medium-low heat should have extra virgin olive oil in it. Heat it until it just starts to shimmer. Put in the garlic, onions, and grated carrots. Stirring often for about 5 minutes, until softened
Put in the tomato paste and about half a cup of water. Sprinkle a lot of salt and pepper on top. Add the crushed pepper flakes and oregano, if you're using them. Last, add the fresh parsley and basil.
Turn down the heat after the sauce has boiled. Put the lid on top and cook for 15 to 20 minutes. If you think the sauce is too thick, you can add a little more water, especially some of the water you used to cook the pasta. If you want, add more fresh basil when the sauce is done
If you are making it for dinner, you can add any cooked pasta you like to the sauce. Add the pasta to the sauce and stir it all together. Cook for about 5 minutes over low heat
