This recipe details how to assemble a classic Italian sub loaded with various deli meats, provolone cheese, and fresh vegetables like onion, lettuce, and tomato. The ingredients are layered on soft Italian bread dressed generously with red wine vinegar and olive oil, creating a flavorful and satisfying sandwich perfect for lunch or a casual dinner. It's a straightforward process with minimal cooking.
Soaking the thinly sliced onion in cold water significantly reduces its raw pungency, leaving just a pleasant onion flavor without the bite. Hollowing out some of the bread interior allows for a better bread-to-filling ratio and helps keep the sandwich more manageable. Layering the dressing between ingredients ensures even flavor distribution. Use high-quality deli meats and cheese for the best results. This sandwich is best assembled just before serving to prevent the bread from getting soggy.
