It has also introduced an “= low carb” logo for packaging, to flag up low carbohydrate convenience food to fans of the Atkins’ diet regime.
The logo was created after experiments with ‘low carb’ stickers on products like salads, which started earlier this year.
M& S is rolling out its first low carb, flour-free, egg and parsley crepe sandwich and extending the range with the launch of five ‘low carb’ Steam Cuisine meals next month. Steam Cuisine menu options in the pipeline include mustard chicken, Scottish salmon, red salmon and chicken and mushroom. Meanwhile, the new low carbohydrate sandwich wraps come in four varieties - red Thai chicken, spicy prawn, goat’s cheese and red pepper and free-range egg and smoked salmon.
All are being launched at special introductory prices of around £2 to £2.50.
They will be priced at between £2.50 and £2.90 when the introductory period finishes.
A spokeswoman said carbohydrate reduction was very much on M& S customers’ minds at the moment.
She added that retailer’s low carbohydrate food-to-go range would be extended if consumer reaction was positive and that the sandwich wraps had proved popular with customers so far.
