In a small skillet, heat the oil over medium-high heat. Add garlic + stir, lightly frying for ~1 minute until golden. Pour the garlic + olive oil into a mixing bowl and allow to cool slightly.
Add the tomatoes, balsamic + basil to the bowl. Sprinkle with salt + pepper. Toss to combine. Taste and add more basil + salt as needed. Cover and refrigerate for ~1 hour.
