The new range, which includes Miso Salmon and Chipotle Chicken options, is 60 per cent larger than existing salads and features premium ingredients.
Pret stated that sales of its salads have grown significantly, three times faster than sandwiches, prompting the introduction of these new protein-packed options.
However, the high price of the "Super Plates" has sparked widespread debate and outrage among social media users, who criticised the cost for a salad.
The new salad range will be available in 250 Pret stores across the UK, including major cities like London, Edinburgh, Manchester, and Birmingham, from Thursday, 9 July.
