With a satisfying chew and complex flavors, this is going to be a big hit with anyone. Best when served hot, but also a yummy lunchbox choice because melting the cheese on the bread keeps it from getting soggy. If you like, add potato chips and a dill pickle on the side.

  • Heat 1 1/2 teaspoon butter and 1 1/2 teaspoon oil in a large nonstick skillet over medium-high heat until hot but not smoking, about 2 minutes. Toss in mushroom slices; season with thyme leaves, salt, and pepper. Cook and stir until mushrooms start to brown and are tender, about 5 minutes. Drizzle soy sauce over mushrooms, toss briefly and transfer to a bowl.

  • Wipe out skillet. Heat remaining butter and oil over medium-high heat until hot but not smoking, about 2 minutes. Toss in peppers and onions; season with salt and pepper. Cook and stir until soft, about 5 minutes. Transfer peppers and onions to the bowl with the cooked mushrooms; toss to combine.

  • Place rolls on toaster oven baking tray. Spread mustard over 2 halves. Place 1 piece provolone cheese over each half. Toast open-faced until cheese is melted, about 3 minutes.

  • Place the toasted rolls on plates and top with mushroom mixture.

Tasty! I like this for something different from a usual meat-style sandwich. I would make this again. Thanks for sharing.:) Read More

Don't miss the steak! These are a huge hit when football season rolls around. I use the baby bellas (some of the photos show the big portobellos) it makes it much easier to eat. I use Worcestshire sauce instead of soy sauce. Read More
