Morrison's value avocados are great - the ones in a green net bag.
They are small and I find they ripen perfectly, though it takes a while.
I leave them for at least five days then put in the fridge to hold them.
I buy some more offbeat meat items at Morrison's too. They are great for that.
I get the pork rind (for making noodles), and trotters sometimes (great for making broth) also beef heart, beef ribs, tripe, ox kidney, etc.
I love nose to tail eating.
