Thanks for the jicama idea. I found one at my store (& learned out to pronounce it!) & it is a nice, good-tasting one. I cut the recipe down to one third since it's just the 2 of us & it turned out great. It's very nice by itself, but it would be good as a topping on lettuce, too.

Beside using jicama, I used avocado oil instead of olive, since I thought that might overpower the veggies.
