Recipe FAQs

What vegetables are best for roasting in this dish?

Zucchini, red bell peppers, and red onions work wonderfully, providing a mix of sweetness and mild tanginess when caramelized.

Can I substitute the bread used here?

Sourdough is recommended for its sturdy, crisp texture, but any rustic bread with a chewy crust can be used.

How can I achieve a crispy crust while melting cheese inside?

Butter the outside of the bread slices and cook on medium heat using a skillet or griddle until golden on both sides, ensuring melted cheese inside.

Is balsamic glaze necessary for this preparation?

While optional, balsamic glaze adds a sweet-tart depth that complements the fresh vegetables and mozzarella perfectly.

Can I add spice to this variation?

Yes, a pinch of crushed red pepper or chili flakes can be added to the vegetables before roasting for a mild heat.
