Great vegetarian sandwich. Can make on outdoor grill, panini press, or skillet. These are even better the next day. From Jenny :)

Ingredients Nutrition


  1. Mix together oil, salt and pepper, and garlic. Marinate mushrooms and onions with this for about thirty minutes.
  2. Grill mushrooms and onions over medium heat until done, brushing on the oil mixture liberally throughout cooking time.
  3. Cut the bread open length-wise, brush it with the oil, then lightly toast on the grill.
  4. Layer on the onions and mushrooms. Press sandwich together for a few minutes (I usually use a frying pan to weigh it down).
  5. Cut into 6 pieces or so and serve.

Made this for lunch today. I did add a slice of provolone. Really enjoyed it.

This was part of our mini panini party. I spread out dozens of ingredients and posted the recipes nearby. Everyone enjoyed this dish, but many thought a few herbs would be great additions -- perhaps basil and oregano.

After reading previous reviews, I went ahead and sliced the mushrooms to let the seasoning get to the inside, and made this in a nonstick skillet, pressed with my heavy skillet lubed with some cooking spray. Worked like a charm! And the taste . . . Oh, heavenly. The bread I picked up was an artisanal sourdough loaf, and the sourness REALLY worked with the mushrooms and onions. Thank you so much for posting, made for ZWT4.
