For entertaining I usually prefer dishes that can be made ahead of time, but I make an exception for this one. It does need to be assembled at the last minute; but when you want something particularly beautiful to start a small dinner party, it’s worth the extra effort. The flavor of mint really shines through and the colors are stunning together, especially if you use a mix of heirloom tomato varieties.
Cooks' Note
Leftover oil can be stored in a covered container in the refrigerator; it will remain flavorful for a day or two. Use it to drizzle on grilled fish and vegetables, on pasta, and in salad dressings for an extra herbal punch.
