In a small mixing bowl, add the garlic, olive oil, vinegar, herbs, and salt. Use a whisk to combine until emulsified. You can also use a small blender.
Arrange the tomatoes on a large plate, slightly overlapping.
Pour the marinade evenly over the tomatoes. Cover with the lid or plastic wrap, and marinate for 2-12 hours. Let come to room temperature before serving, for best flavor.
Notes
*Note 1 - Any varietal of tomato will work. *Note 2 - other good vinegar options: red wine vinegar, white wine vinegar, and apple cider vinegar.*Note 3 - If you only have dried herbs, use 1 tsp. in place of the fresh herbs.
