I don't like shops such as Iceland who are promoted as selling family food when the majority of their food is processed, turkey twizzler type food. Iceland doesn't even sell frozen fruit.
We have garden centres locally with greengrocer's shops attached, and not only can you buy fresh, locally produced fruit and veg but you can also buy frozen. I like the frozen fruit pick and mix; there are selections such as red berries, tropical fruit and such, you scoop them into bags and buy by weight.
