As British Sandwich Week 2026 kicks off, chef and author Amy Sheppard has shared a selection of sandwich recipes to mark the occasion. Known for her work on Sun on Sunday and her cookbook "Easy 10," Sheppard offers four varied sandwich ideas designed to appeal to a wide range of tastes.

One of the highlighted recipes features a cheese, pastrami, and jammy onion Marmite panini served with homemade straw chips and a green salad. The preparation begins with frying sliced onions in sunflower oil until translucent, then incorporating brown sugar and Marmite to create a savory jam. Thinly sliced potatoes are soaked to remove starch before being deep-fried until golden, serving as a crispy side.

The panini assembly involves layering cheddar slices, slivers of pastrami, and the Marmite-infused onions between split panini rolls. These are then pressed firmly and toasted in a lightly oiled pan or air-fried for several minutes to achieve the desired crispiness. The finished dish balances rich flavors from the cheese and pastrami with the umami of Marmite and the sweetness of the onion jam, complemented by the crunch of the straw chips.

Sheppard describes the sandwich as suitable for dinner despite its lunchtime appearance, noting that some of its components can be adapted for other recipes during the summer months. Her contribution to British Sandwich Week underscores the versatility and broad appeal of the sandwich as a meal option across different occasions.

British Sandwich Week is an annual event celebrated across the UK, promoting the sandwich as a convenient and varied food choice. Chefs, food writers, and retailers often use the week to showcase innovative sandwich ideas and inspire both consumers and industry professionals.
