Bocadillo de verduras is a Spanish sandwich made with a hunk of bread that's filled with a variety of vegetables, usually roasted. The sandwich typically consists of a ciabatta bread roll or a Spanish-style baguette (barra de pan) that's been cut in half along the middle and filled with vegetables.
Typical vegetables for the sandwich’s filling include zucchinis, peppers, eggplants, carrots, tomatoes, onions, artichokes, salad greens, broccoli, cauliflowers, and peas. The bread is sometimes broiled for added crispiness, while the sandwich's filling may also be enhanced with other ingredients such as queso de cabra (goat cheese) or queso fresco (fresh cheese), slices of salami, mushrooms, or eggs.
