Ingredients

Large portobello mushroom cap

Deli roll or good hamburger bun

1/2 Roasted Red pepper, stored in oil

Marinade:

1 T Olive oil

1 T Balsamic vinegar, plus a very small amount for mayo

Chipotle Mayonnaise:

Salt & freshly ground pepper

1 T Mayonnaise

1/8 t Ground Chipotle powder (or to taste)

Preparation

Clean mushroom cap and remove remaining stem.

Combine oil, vinegar and salt & pepper to taste and beat slightly. Pour over mushroom cap. Allow mushroom to marinate at least 1/2 hour.

In a small dish, mix maynonnaise, chipotle powder and a small amount, maybe 1/8 t of Balsamic vinegar. Refrigerate.

Prepare an indoor grill to about 300F and grill until tender, about 10 minutes with a dual-cooking surface countertop grill.

Toast roll/bun and spread both sides with the Chipotle-Balsamic mayo. Add mushroom and top with the roasted red pepper (do not rinse–the oils add wonderful extra flavor).
