In a large bowl, combine diced tomatoes, olive oil, chopped garlic, flaky sea salt, and julienned basil leaves.
Stir well, then taste and adjust seasoning as needed.
Store in an airtight container in the fridge. However, keep in mind that the texture of the tomatoes may soften more. Leftover bruschetta is best enjoyed within 24 hours for optimal taste and freshness. If enjoying with bread, toast fresh slices before serving.
