Ingredients

Quantities are for 4 servings.

You'll need: Stovetop.

Uses cooked sliced roast beef for a practical home version; warm it gently in jus so the slices stay tender.

Method

  1. Heat oil in a pan and cook the sliced green bell pepper until softened.

  2. Add garlic briefly, then pour in beef stock with oregano, paprika, chilli flakes, salt, and black pepper.

  3. Simmer the jus until aromatic, then add the sliced beef and warm it gently without boiling hard.

  4. Fill each roll with warm beef and peppers.

  5. Spoon a little jus over the sandwich and top with giardiniera.

  6. Serve immediately with extra jus for dipping if desired.

How to tell it's done

The roll should be juicy but not collapsed, with tender beef and crisp-tangy giardiniera.

Getting it right

Tip

Warm the beef gently in the jus; boiling it hard can make thin slices tough.

What to serve it with

Serve with potato chips, pickles, or a simple salad.

Common mistakes

The beef turns tough and grey.
Warm it in the jus below a simmer and take it out as soon as it is hot. This is already-cooked roast beef sliced thin; boiling it in stock squeezes it dry in under a minute.
The roll disintegrates.
Dip briefly and eat immediately, or serve the jus alongside for dipping. A roll left standing in jus has no structure left by the time it reaches the table.

Substitutions

  • Giardiniera — Pickles can add tang if giardiniera is unavailable, but the sandwich will taste less Chicago-style.
  • French Bread Roll — Use Hoagie Roll if needed, but choose a sturdy roll that can hold the jus.

Storing and reheating

The beef and jus keep three days in the fridge together and freeze for two months — store them as one, since the beef dries out on its own. Rolls and giardiniera go on fresh; a built sandwich does not keep at all.
