Heat the oil in a medium pan over medium-high heat. Add the tomatoes and let them sit undisturbed in the pan for 2 minutes, to blister on the bottom.
Add the garlic, salt, and pepper, then stir together with the tomatoes. Let them cook and blister another 2-3 minutes, stirring a few more times.
Remove the blistered tomatoes from the heat, then top with chopped basil or other fresh herbs.
Serve with grated parmesan, if desired
