Princes Foods is extending its Ready to Go Tuna pouch range with the launch of a tuna and light mayonnaise variety. Women are the key target for the newcomer which is due to hit shelves next week. Its low fat content is expected to appeal to those who are trying to lose weight (said to be around 65% of women at any one time). Like the original range, the new pouch contains a single sandwich or baked potato portion, so consumers can use and lose' the packaging. But at 100g it is slightly bigger to allow for the right balance of tuna and mayonnaise. Rsp: 79p. {{P&P }}
