Well, Papaya is not only used when it is ripe. Some people eat Papaya when it is green as well. Since most of us might not this growing in our backyard, you can check your local supermarket when they have this fruit not fully ripe and try this delicious salad.
You use it like you would zucchini. Use the dark green papayas. (make sure you don't see any yellow on it )
1-2 green papayas, peeled and cut into julienne strips
use strips of celery or you can use some celery seeds

3 scallions, chopped up

In a bowl, toss together the celery, peppers, and onions. Add the papaya.
you can use a nice vinaigrette salad dressing. or a balsamic dressing.
