1 red pepper cut in quarters lengthwise
1 small red onion cut into 4 slices
2 portobello mushroom caps
1/2 cup extra-virgin olive oil
Salt and pepper

Instructions
Preheat grill. Use a brush to brush olive oil on all of the vegetable slices. Season with salt and black pepper.
Place vegetables on a hot grill and cook until they are tender.
Brush each side of the roll with olive oil. Grill both sides lightly.
To assemble, slice portobellos into 1/4-inch slices, spread both sides of the grilled bread with mayonnaise and then top with 1 slice each of grilled vegetables and a quarter of the mushrooms, and finish off with lettuce and top with remaining half of the roll.
