Cut the brie into several small pieces and remove the rind with a paring knife. If you like the rind and want to leave it on, I’m not gonna shame you. Set aside.
Saute’ the mushrooms in a skillet with the oil, crushed garlic, salt, and pepper for about 10 minutes over medium heat. Remove from heat, and add onion powder.
Transfer to food processor or blender and chop into small bits. If your don’t have either, use a knife and cutting board.
Combine with the Brie in a bowl. Using a sharp knife, chop and combine for 3 minutes. Use a big spoon to blend into a creamy paste.
Spread on cheese crisps, celery, flax crackers, fat head pizza crust, or your favorite fat delivery vehicle.
