Ingredients

• 4 large caps Portobello mushrooms
• 3 tablespoons Olive oil
• 2 tablespoons Balsamic vinegar
• 1 tablespoon Soy sauce
• 2 cloves Garlic
• 0.5 teaspoons Ground black pepper
• 0.5 teaspoons Salt
• 4 whole Ciabatta rolls
• 0.5 cup Mayonnaise
• 1 tablespoon Dijon mustard
• 1 cup Arugula leaves
• 1 large Tomato
• 0.5 medium Red onion

Directions

Step 1

Clean the portobello mushrooms by wiping them with a damp paper towel to remove any dirt. Remove the stems.

Step 2

In a shallow bowl, whisk together olive oil, balsamic vinegar, soy sauce, minced garlic, black pepper, and salt to create the marinade.

Step 3

Place the portobello mushrooms in the marinade, turning them to ensure they are well coated. Let them marinate for 10 minutes.

Step 4

While the mushrooms are marinating, slice the ciabatta rolls in half horizontally and set aside.

Step 5

In a small bowl, mix together the mayonnaise and Dijon mustard until well combined. Set aside.

Step 6

Slice the tomato and the red onion thinly. Set aside.

Step 7

Heat a grill pan or skillet over medium-high heat. Once hot, add the portobello mushrooms and cook for about 5-7 minutes on each side, or until tender and caramelized.

Step 8

Toast the ciabatta rolls on a separate pan or in a toaster until golden brown.

Step 9

To assemble the sandwiches, spread a layer of the mayonnaise and mustard mixture on the bottom half of each ciabatta roll.

Step 10

Place a cooked portobello mushroom cap on top of the sauce. Add a handful of arugula leaves, a few slices of tomato, and red onion.

Step 11

Top with the other half of the ciabatta roll. Serve immediately and enjoy your vegetarian classic steak sandwich.
