Oh, peas! Yes, peas can be great. Lychees I've never had fresh.
There was an article in the New Yorker a while back about a guy who goes around finding strange fruits and convincing grocers in the US to sell him. He's the one who found this fuzzy little green thing called a Chinese Gooseberry and decided to call it a "kiwi".
(Seriously!)
Anyway, he said something about... peaches?... to the effect that people who only eat the supermarket version, never fresh, are miserably deprived. I think there are many fruits/ veggies that are just fine in the supermarket version, but divine freshly picked.
Mango seems to travel well...
