The Great British Sandwich Study: The most-loved UK sandwiches named as Gen Z turn away from classic fillings

• Bread company Allinson’s conducted research by asking 2,000 Brits of their sandwich choices
• Mayonnaise was a clear winner of condiment of choice
• The generations were split on whether to include crisps in a sandwich

Britain's favourite sandwich has been revealed, according to a study by bread company Allinson’s.

The Great British Sandwich Study found that there has been a growing interest in fillings such as avocado, olives and mozzarella.

According to Allinson’s, traditional fillings such as ham and cheese are not as enjoyed by Gen Z, who prefer to enjoy a sandwich with a “fancy” filling.

Research was conducted by asking 2,000 Brits of all age groups on their favourite sandwiches, including their bread of choice, fillings and slice preferences.

The study highlighted the growing trend of sandwiches with more “exotic” ingredients, rather than the traditional classics.

26% percent of people in the Boomer generation said they love sliced ham in their sandwich, while 31% Gen Z said they prefer chicken.

When it comes to a traditional ham and mustard sandwich, one in 10 Boomers said they would pair the ingredients together, while only one in 100 said they would from Gen Z.

Different types of cheese are also enjoyed, with 66% of Boomers choosing cheddar, and 48% of Gen Z choosing continental cheese.
