Line a baking sheet with aluminum foil and set aside.
Quarter the tomatoes and place them on the baking sheet cut side up. Drizzle each tomato quarter with olive oil, then sprinkle with sugar, salt and freshly ground black pepper.
Roast for 35-40 minutes or until the tomatoes begin to caramelize.
Turn the oven off and move the pan to the lowest oven rack.
Leaving the oven door ajar, let the tomatoes rest in the oven for 30 minutes.
Serve warm as a side dish sprinkled with the cheese of your choice, and a drizzle of balsamic glaze if you like.
Notes
These tomatoes can be enjoyed as a side dish, on pizza, tossed with hot pasta or on toasted bread as a sandwich.
