Preheat the grill to medium-high heat.
Slice the zucchini and yellow squash lengthwise into 1/4-inch thick strips. Cut the red bell pepper into large flat pieces by removing the stem, seeds, and membranes. Remove the stems from the portobello mushrooms.
In a large bowl, toss the zucchini, squash, red bell pepper, and mushrooms with olive oil, salt, and black pepper until evenly coated.
Place the vegetables on the preheated grill. Cook for about 3-5 minutes on each side, or until tender and slightly charred. Remove from the grill and set aside.
Cut the ciabatta rolls in half and lightly grill the cut sides for about 1-2 minutes, or until toasted.
Slice the avocado in half, remove the pit, and scoop out the flesh. Mash it in a small bowl and season with a pinch of salt for flavor.
To assemble the sandwich, spread the mashed avocado evenly on the bottom half of each ciabatta roll. Layer with grilled zucchini, yellow squash, red bell pepper, and portobello mushrooms.
Top each sandwich with 2 fresh basil leaves and a slice of provolone cheese. Drizzle a small amount of balsamic glaze over the vegetables.
Close the sandwich with the top half of the ciabatta roll and serve immediately. For extra flavor, you can secure the sandwich with a toothpick or skewer before serving.
