Let's Make it Together
Create the Marinade: In a bowl, whisk together balsamic vinegar, olive oil, minced garlic, chopped herbs, salt, and pepper until well combined. This marinade will bring life to our mushrooms.

Grill Those Burgers: Place marinated mushrooms on the grill gill side down. Grill for 5-7 minutes until tender and juicy while basting occasionally with leftover marinade.
