Yes! And easily, too!
The fermentation and preservation of foods with salt and pepper (aka 'pickling') is fun, easy and has been done for-flippin'-ever without nasty chemicals.
Here's a simple one:
1 c. sugar
1 c. vinegar, apple cider vinegar
1 c. water
1 heaping tbsp. mixed pickling spices
Put spices in small bag. Boil all together.
I have used this recipe to pickle, cucumbers, carrots, brussels sprouts, pineapple, pears, peaches, beets, hard boiled eggs, prunes and figs and apple rings. Just drop fruit in the brine and simmer for about 10 minutes, gently.
