Break down the tomatoes: Using your hands squish the tomatoes in a bowl, or use kitchen shears to break down the tomatoes into smaller pieces. You could also just use an immersion blender and just pulse it so the tomatoes are smaller.

Cook the aromatics: In a saucepan over medium heat, add the grated onions, and the dried seasonings. Allow the oil to cook the onions for around 3-4 minutes, stirring frequently so nothing sticks or burns. Then, add the garlic and continue to cook for another 30 seconds.

Simmer the sauce: Add the tomatoes along with the sugar and salt and allow the sauce to come to a simmer, then lower the heat and allow for it to cook for 30 minutes. You can taste the sauce and adjust with additional seasoning or salt as desired. You could also simmer the sauce for longer should you find it needs to be a little more concentrated for your taste.
