Add a tablespoon or so of olive oil into a hot pan over medium-high heat and throw in the garlic and chopped onions and give them a stir.
Add the crushed tomatoes and stir to combine. Add salt and pepper to taste and a pinch of sugar. Reduce the heat to low and simmer for 30 minutes.
Toward the end of the cooking process, chop up your fresh parsley and basil and add it to the sauce to taste, stirring to combine.
