Combine all ingredients, except tomatoes, in a large glass bowl. Whisk to combine, then add tomatoes. (You can up the quantity of tomatoes if need be.) Use regular red tomatoes, or a mixture of red, yellow, heirloom, etc. Use different sizes of tomatoes, too–pretty!

Allow to marinate for at least 3 to 4 hours, several hours if possible. Tomatoes will give off liquid as they marinate.

Use leftover tomatoes to make bruschetta: slice baguette and brush slices with olive oil. Grill on a skillet or grill pan until golden. Rub slices with garlic cloves. Top with tomatoes, allowing juice to drip on the bread.
