Pesto?

[Devonian]

I've never seen tins of pesto, or in fact anything other than the small jars like you have got from Asda.

In the US you can get a dried Pesto mix made by Knorr, but again I don't think it's available over here.

Some of the main supermarket brands I find pretty poor quality (not tried the asda one) and are just packed full of cheap oil, but the Lidl one which is a similar cost to your Asda one is not bad.
