Instructions
- Remove portobellos stalks. Mix all the ingredients to marinate the portobellos. Using a cooking brush, toss them with the sauce on both sides. Let them marinate for 30 minutes, with the cap side down.

Notes
- Portobellos are my favorite choice when going to BBQs or inviting friends over. They are extremely delicious, juicy and adaptable to any kind of add-on that you can think of. Just get creative by adding different seasonings, vegetables or even some melted cheese.
