I typed "Banana" peppers into my search engine to find recipes- I guess they are also called "Hungarian" peppers.
I also found a recipe in the Ball Blue Book for "Pickled Peppers" (it doesn't specifiy sweet green pepper, but I'm sure you could substitue the them in).
4 qts long red, green or yellow peppers (Hungarian, Banana or other varieties)
1 1/2 cups canning salt
4 qts plus 2 cups water, divided
1/4 cup sugar
2 Tbsp prepared horseradish
2 cloves garlic
10 cups vinegar
Cut two small slits in each pepper. Dissolve salt in 4 quarts water. Pour salt water mixture over peppers and let stand 12-18 hours in a cool place. Drain; rinse and drain thoroughly. Combine 2 cups water and remaining ingredients in a large saucepot. Simmer 15 minutes. Remove garlic cloves. Bring pickling liquid to a boil. Pack peppers into hot jars, leaving 1/4-inch headspace. Ladle hot liquid over peppers, leaving 1/4-inch headspace. Remove air bubbles. Adjust two-piece caps. Process half-pints and pints 10 minutes in a boiling-water canner. Yield: about 16 half-pints or 8 pints.
I hope this helps: we wouldn't want all those peppers to go to waste!! Good luck!
