In a medium skillet, preheat the olive oil over medium heat. Season the snapper fillets with salt and pepper on both sides. Add the snapper fillets and sear them with skin up. Add all remaining ingredients except the brandy, cheddar cheese, and butter. Simmer for approximately 2 minutes, turning the snapper over after it reaches a nice golden brown color. Add the brandy to the skillet and top the snapper with the cheese. Cover for 1 minute to melt the cheese. Remove the snapper from the skillet and set aside. Finish the sauce by slowly stirring in the butter. Place 2 snapper fillets on each plate and top the plated snapper with the sauce.
