Out of the three, I would prefer raw peas.
However the last few years it is so difficult to get good ones and even in the expensive shops, some of the peas inside the pod are so small that I end up wasting half of them.
I remember when they were plump and large and are beautiful to just eat raw as you get them out.
My second preference would be raw carrots with beans being last.
I do not like frozen peas -for some reason they just do not taste the same, and I do not think they are nice eaten raw.
