Do you ever use them in salads?
Are you supposed to cook 'em first?

Yes and yes - in Salad Nicoise recipe
Quick/brief cooking, chill in freezer or fridge while preparing other ingredients.

Sent you a PM with a more detailed recipe. Recipe says blanched which is cooked briefly - I zap frozen for 4 - 5 minutes in microwave.
Thanks MW, I just read the updated recipe, That would be a good "Rob & Randy" lunch because they could help me with the prep work.....and it's low carb.
Scrubb, throw 'em out, After a year beans go stale and have a mealy constistency.
Seriously, whadya pay? A buck a bag, maybe?
Canned goods will last a long time but I wouldn't go beyond 2 or 3 years past the expiration date.
There's a website devoted to this. www.stilltasty.com I think is the name of it.

Green beans,string beans and long beans blanched in boiling water for a minute or two stores quite well in the freezer for later use in salads.
Quite often used in Indonesian "gado gado" salad/ulam dish with spicy hot chunky peanut butter satay sauce.

I make a salad with green beans (flat ones if possible like these cooked a short while so they are still crisp, with tomatoes and a bit of basil. Vinaigrette dressing. I got the recipe from an Italian friend.
Manch, surely you've had good old three-bean salad?
This time of year, don't even think of frozen beans. Trim the ends off fresh beans, boil a large pot of water, throw the beans in & cook for about 5 minutes at a boil. After 3 minutes, start tasting. Once you've done that a couple of times, you'll know how long it takes beans to cook to the degree you like them.
While the beans are cooking, fill a bowl with water & ice cubes (not water alone, not ice alone). When the beans are done drain them, and immediately put into the ice water for a few minutes. Don't leave them int he water forever. Refrigerate in a baggie for no more than a day or two.
This is a favorite of mine. You could use all green beans if you want, but the yellow beans make it more attractive. Green Bean, Yellow Bean and Cherry Tomato Salad
