Add the cherry tomatoes to a bowl. Add the oil, oregano, garlic cloves, salt and pepper. Toss to coat and turn out onto a rimmed baking sheet.
Roast until tomatoes are blistered and begin to burst, 20–25 minutes.
Taste for seasoning and season with salt as needed. Top with fresh herbs before serving.
Notes
Instead of using garlic cloves whole you can mince the garlic or even finely chop it, but be aware that it might char and burn and change the flavor of the tomatoes.
You can add chunks of chopped onion to the roasted cherry tomatoes to add extra flavor.
If you like things spicy add some flaked red pepper or a pinch of cayenne.
Crumble some feta cheese or mozzarella over the cooked tomatoes and serve with ciabatta for a homemade bruschetta.
