Did you know Iceland sells frozen avocados?
If you love Avacados, Iceland sells them pre-peeled and without the stone.
You can get a bag of 6-8 halves for £3.50.
They're large and really you're paying for the convenience factor.
I tried them with making smoothies. Take one out, plonk it in the blender, done.
There's been quite a bit of media recently about people having to buy tiny avocados no bigger than an egg.
This is a good way of always having decent sized avocados.
