Remove the stems from the portobello mushrooms and gently clean the caps with a damp paper towel to remove any dirt.
In a shallow dish, combine 3 tablespoons olive oil, balsamic vinegar, minced garlic, salt, and black pepper. Whisk to combine.
Place the mushrooms in the marinade, turning to coat both sides. Let them marinate for at least 15 minutes while preparing the other components.
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.
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.
While the mushrooms are grilling, lightly toast the sandwich rolls or ciabatta bread halves on the grill.
To assemble the sandwich, spread a generous layer of basil aioli on the cut sides of the toasted bread.
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.
Serve the sandwiches warm with your favorite side dish, such as a crisp salad or sweet potato fries.
