Preheat oven to 375. Place cheese in the middle of a medium sized cast iron skillet.
Warm vinegar in a pot over medium-low heat until hot. Add fig jam and stir until jam is thin and syrupy. Brush half of the mixture over brie in a thick layer.
Mix nuts, sliced dried figs, and remaining fig jam mixture in a bowl. Spoon over top of cheese, creating a thick layer. Mixture will fall off on to side, that's okay!
Bake uncovered for 10 minutes, until brie is soft inside. Let sit for about 5-10 minutes to let cheese rest for a bit and cool before you cut into it. Finish with salt and serve with your favorite crackers.
