Arrange the tomatoes on a wide platter. Top with the capers, feta and oregano. Drizzle and sprinkle with oil, vinegar, salt and pepper. Let salad sit a few minutes to allow the flavours to meld, and then serve.
Note: If desired and available, used a mix of coloured on-the-vine tomatoes in this recipe, such as red, yellow and orange.
Recipe Options: If you don’t care for capers, sprinkle some coarsely chopped black or green olives, to taste, over the tomatoes. Instead of fresh oregano, use fresh basil on the salad. Instead of feta cheese, try small nuggets of soft goat cheese on the salad.
