Refrigerated in a plastic bag, they should last at least about a week to ten days.
If you won't get around to eating them right away, peas are very easy to freeze. Blanch in boiling water for 1 minute, followed by an ice bath. Drain the and place them in a ziplock bag in the freezer.
Because they are so sweet, peas are great raw and are most often used in salads. Their flavor, texture and color can also all be improved by cooking – most simply steamed, or sautéed in olive oil with a bit of salt and pepper or added to any kind of stir fry.
Both Snow Peas and Sugar Snap Peas have edible pods and are delicious to eat whole and raw. Just pop the top off and peal the string down the side.
