TL;DR
A recent taste test evaluated various supermarket ham and cheese sandwiches, revealing that most contain additives and lack transparency on welfare standards. The best option was from M&S, while an inedible product from Waitrose was the worst.
A recent evaluation of supermarket ham and cheese sandwiches has rated the products based on quality, additives, and welfare standards, with the top choice from M&S and one product deemed nearly inedible from Waitrose.
The review assessed multiple sandwiches from major UK supermarkets, focusing on ingredients, additives, and animal welfare claims. The M&S honey-roast ham & cheddar cheese was rated the best overall, featuring minimal additives and clear welfare standards, despite containing palm oil. Conversely, a product from Waitrose, the Spanish serrano ham & cheese rosca, was found to be elaborately awful and nearly inedible, containing multiple additives and scant ham. Most products used reformed ham with added phosphates and water, and all contained some additives. Transparency on animal welfare was generally lacking across brands, with some claiming higher standards without certification. The review highlights concerns about ingredient quality and transparency in supermarket offerings.
Why It Matters
This review matters because it sheds light on the quality and transparency of supermarket meats, influencing consumer choices and raising questions about animal welfare standards and ingredient transparency in everyday shopping.

Background
Supermarket meats often rely on reformed, processed options with added water, phosphates, and additives. Consumer awareness of animal welfare standards varies, with many products lacking certification or clear information. Previous evaluations have called for greater transparency and better quality standards in retail meats, but widespread issues remain. This review provides an updated snapshot of current offerings and quality concerns, reflecting ongoing debates about food transparency and ethics in the UK retail sector.
“Most of the sandwiches feature reformed ham, which is bulked out with phosphates and water, but some higher-quality ones are made with real ham—shredded ham hock or sliced meat without added water.”
— Food reviewer
“The worst product, from Waitrose, was described as ‘elaborately awful and all but inedible,’ which underscores the variability in quality and the risks of heavily processed foods.”
