Preheat the oven to 400 degrees F.

Step 2

Lightly grease a 9-by-13-inch baking dish with some cooking spray, then set aside.

In a large bowl, whisk together the olive oil, vinegar, garlic, salt and pepper. Add the tomatoes and peppers and toss to coat.

Bake until the tomatoes and peppers are soft and starting to brown, about 35 minutes.

Top with torn basil leaves and serve warm.
