A recent review of supermarket ham and cheese sandwiches has identified the best and worst options on the market, highlighting significant differences in quality, ingredients, and transparency.

The top-rated product was M&S honey-roast ham & cheddar, praised for its minimal additives and clear welfare standards, despite containing palm oil. It was the only product with just three additives and transparent sourcing.
In contrast, the least appealing was a Spanish serrano ham & cheese rosca, described as “elaborately awful and all but inedible,” with multiple additives, scant ham, and no welfare data. Several products, including those from Asda and Sainsbury’s, contained numerous additives and lacked clear animal welfare information, raising concerns about transparency and quality control.
