Add the garlic, vinegar, water, sugar, basil, and oregano to a large saucepan. Over medium heat, bring to a boil. Once boiling, lower the heat to low and simmer for 5 minutes.
In the meantime, pack the chopped tomatoes and onions into clean mason jars. Once the vinegar mixture has simmered for 5 minutes, ladle it into the jars, covering the tomatoes. Remove any air bubbles and top up the brine, leaving 3/4 of an inch of headspace.
Place a lid on the jar and waterbath can the jars for 10 minutes. Remove the jars from the canner and allow them to fully cool on a wire cooling rack covered with a clean tea towel for 24 hours. Once cooled, wash and dry the jars. Label and store in a dark, cool pantry.
When ready to serve, drizzle with a little balsamic vinegar and olive oil. Season with some flaked sea salt.
