Usually, I just defrost some frozen peas for about an hour, de-shell and then mush them up and put in little amounts at a time for my White Cloud Mountain Minnows. I don't bother with boiling them or microwaving them, partly because in the week I do the feeding as soon as I'm home from work; I'm very particular about what I've had on my hands, such as soap (and do I rinse them under cold water a lot to make sure I'm not poisoning my fish), so I keep the mucking about to the minimum. I'm now worrying that maybe something in the peas might be poisoning the fish (not that I've noticed anything *touch wood*) from the method I'm employing. I've been feeding pea this way for a few months now, and I'm now doing it regularly in the week (about 2 times - I feed every other day, and have recently decided it's best to make every other feeding pea).
