Recipe Help

What vegetables are best for roasting in this dish?

Zucchini, red bell pepper, and red onion are excellent choices, offering sweetness and texture that caramelize well when roasted.

Can I use a different type of bread?

Sourdough is recommended for its sturdy texture and flavor, but hearty artisanal breads also work well to hold the fillings.

How long should the vegetables be roasted?

Roast the vegetables for 18 to 20 minutes at 425°F, flipping halfway to ensure even caramelization and tenderness.

Is the balsamic glaze necessary?

The balsamic glaze adds a tangy sweetness that enhances the flavors but can be omitted or substituted with a light drizzle of olive oil if preferred.

Can seasonal vegetable variations be used?

Absolutely. Eggplant, mushrooms, or other seasonal vegetables can replace or complement the original selection for a personalized touch.
