In a large pot set over high heat, add the garlic and sautee for just a minute. Add the chopped onions and sautee on high for 3 - 4 minutes until browned. Reduce heat to medium and continue to cook onions for about 30 minutes until soft.
Increase heat to high and add the tomatoes. Stir well and bring to a boil. Reduce heat to medium and leave to cook until almost all the liquid evaporates, about 1 1/2 to 2 hours. Stir occasionally while the tomatoes are reducing
Add the tomato paste, oregano, basil, sugar, salt and pepper. Give a good stir and leave to simmer for about 10 - 15 minutes.
Remove from heat and blend in batches.
Sauce can be used straight away, refrigerated, frozen or jarred.

Notes
If the onions start to stick while they are cooking, add small amounts of the juice from the canned tomatoes and stir to prevent sticking.
You will know the sauce is done, when almost all the liquid has evaporated from the tomatoes. It's important to get most of liquid out to ensure a rich and thick sauce.
Sauce will keep in the refrigerator up to 4 - 5 days, in the freezer for about four months or jarred up to a year.
