Ingredients

• 4 large caps Portobello mushrooms
• 4 tablespoons Olive oil
• 2 tablespoons Balsamic vinegar
• 2 minced Garlic cloves
• 1 teaspoon Salt
• 0.5 teaspoon Black pepper
• 0.5 cup Mayonnaise
• 0.25 cup Fresh basil leaves
• 1 tablespoon Lemon juice
• 4 pieces Rustic sandwich rolls or ciabatta bread
• 4 large Tomato slices
• 1 cup Baby spinach or arugula
• 4 slices Red onion rings

Directions

Step 1

Remove the stems from the portobello mushrooms and gently clean the caps with a damp paper towel to remove any dirt.

Step 2

In a shallow dish, combine 3 tablespoons olive oil, balsamic vinegar, minced garlic, salt, and black pepper. Whisk to combine.

Step 3

Place the mushrooms in the marinade, turning to coat both sides. Let them marinate for at least 15 minutes while preparing the other components.

Step 4

To make the basil aioli, combine mayonnaise, fresh basil leaves, lemon juice, and 1 tablespoon olive oil in a food processor or blender. Blend until smooth. Adjust seasoning with a pinch of salt if needed.

Step 5

Preheat a grill or grill pan over medium-high heat. Once hot, place the marinated mushrooms on the grill, gill side up. Grill for 4-5 minutes per side or until tender and slightly charred.

Step 6

While the mushrooms are grilling, lightly toast the sandwich rolls or ciabatta bread halves on the grill.

Step 7

To assemble the sandwich, spread a generous layer of basil aioli on the cut sides of the toasted bread.

Step 8

Place a grilled portobello mushroom on the bottom half of each roll, followed by a tomato slice, a few red onion rings, and a handful of baby spinach or arugula. Top with the other half of the bread.

Step 9

Serve the sandwiches warm with your favorite side dish, such as a crisp salad or sweet potato fries.
