Start your campfire or heat up your grill so that your heat source is ready. If using wood or charcoal, let the flames die out prior to cooking your food.
( Optional) Preheat your cast iron skillet over the fire while getting your supplies ready.
Slice your cherry tomatoes in half.
Drizzle olive oil in the bottom of your cast iron skillet.
Place wheel of brie in the middle of the skillet and top it with the halved tomatoes, allowing them to spill around the sides as well.
Add a good sprinkling of kosher salt.
Set the cast iron skillet on a grate over the fire and allow it to cook until the brie has puffed up and the tomatoes have blistered (roughly 20 minutes).
Pull the skillet off the fire and sprinkle it with some fresh chiffonaded basil.Then drizzle it with some balsamic glaze.
Serve with baguette slices, assorted crackers, and/or fresh veggies.
