Sautéed Balsamic Mushrooms are an amazingly tasty snack or appetizer, ready in only minutes!
Combine balsamic vinegar and brown sugar. Set aside.
In a medium sauté pan, heat butter with the olive oil over medium heat. Add mushrooms and garlic, stirring frequently about 2 - 4 minutes until mushrooms have absorbed the oil and butter.
Add balsamic and brown sugar mixture over mushrooms, stir frequently for about 2 minutes or until mushrooms have caramelized from the vinegar and sugar (your parsley can be added at this stage as well, or reserved for garnish).
Turn off heat, add salt & pepper to taste. Top with Parmesan cheese and fresh chopped parsley (optional). Serve immediately while hot, or refrigerate for serving cold.
