Recipe Help

What vegetables are best for roasting in this sandwich?

Zucchini, red bell pepper, and red onion roast beautifully, caramelizing nicely while retaining texture. Seasonal veggies like eggplant or mushrooms can also be excellent alternatives.

How can I ensure the bread stays crisp and not soggy?

Butter the outsides of the sourdough slices before toasting and cook over medium heat. This creates a golden, crisp crust that holds up well to the moist fillings.

Is balsamic glaze necessary for this dish?

While optional, a light drizzle of balsamic glaze enhances the sandwich with a sweet and tangy contrast, complementing the roasted vegetables and fresh mozzarella.

Can this sandwich be made vegetarian?

Yes, this sandwich is naturally vegetarian, featuring fresh mozzarella and roasted vegetables without any meat ingredients.

What’s the best way to melt the mozzarella evenly?

Cooking the assembled sandwich on a skillet over medium heat for a few minutes on each side allows the cheese to melt evenly while the bread crisps perfectly.
