In large bowl, combine cherry tomatoes and garlic , then toss with olive oil.
Season to taste with salt, pepper and red pepper flakes.
Place brie in cast Iron skillet then top with tomato mixture.
Place on hot grill and cook until brie is melted, about 20 minutes. (Just because it isn’t oozing, doesn’t mean it’s not hot and ready, to test just poke sides with a knife to see if cheese is melty inside).
Drizzle with balsamic glaze and garnish with basil.
