Preheat oven to 400°. Cut the tomatoes in half and place on a baking tray. Place a slice of garlic on each tomato half and sprinkle lightly with salt & brown sugar. Roast in over for 45 minutes, or until dry.
Arrange roasted tomatoes, olives & feta on a serving platter. In a small bowl, combine chile oil, olive oil & lemon zest. Drizzle evenly over tomato mixture. Top with basil leaves & serve.
