Eat right 4 your type O

I am a UK reader of the book and have some difficulty interpreting some og the US phrases and user words into the UK equivalent.
However, I have found no mention of 'peas'. (ie. peas that come in a pod)
It seems to have escaped me whether or not I have seen peas in pods in the States. I do remember mange tout and Sugar snap peas though. Can anyone help? Tweet
