Tescos. Bought recently on a two for one offer . I thought I read they are sin free. Much nicer and less time consuming then making your own. You can have as little or as much as you need(i`e if different family members are eating, you can adjust portion sizes easily). Have tried making my own but it never mixes together as well as Aunt Bessies .
I quite agree that frozen fruit and veg have an important place in our lives, especially for busy working folks.
Personally I would make it myself and would add a boiled potato to mash it that way ensuring that it mixes together well.
I love it with lots of black pepper.........yummy.
I might get some of this to try, I love Carrot and Swede mash but everyone else in this very picky household likes their vegetables kept separate and dont like the swede bit.
