• 1 large Granny Smith apple
  
• 2 medium or one large zucchini
  
• 2 or 3 large carrots
  
• about half a jicama
  
• yellow prepared vegan mustard (the generic American hotdog kind)
  
• balsamic vinegar
  

Here's something I like to make with jicama. It also uses
zucchini, which is a good thing this time of year if you garden.
This is approximate -- I don't have a real recipe and it's
different each time.

This makes a lot. It's sort of a sweet and sour taste, more sweet
than sour. Some people may like it better with the veggies chopped
instead of shredded -- it depends on how much texture you like it
to have. It's better in the first couple of days, before it gets
soggy. To keep it a little longer, leave out the zucchini. The
vinegar (I guess) keeps the apple from going brown quickly.

I've been thinking this might be good with some freshly grated
ginger, in addition or instead of the mustard.

Peel the zucchini, carrot, and apple or not, according to taste.
Definitely peel the jicama. :-P Cut the jicama into matchsticks.
Shred the apple, carrots, and zucchini in the food processor or with
a grater. Mix the veggies and add mustard and vinegar to taste.
I think I used about 2 teaspoons of mustard and 2 or 3 tablespoons
of vinegar.
