They're definitely an acquired taste.

If you didn't grow up eating nopalitos, you could hardly be blamed for not thinking the spine-covered pads of the prickly pear cactus are delicious.

And if you did grow up eating them, well, there's always the slime.

"People just try to hide it or don't talk about it," said Amy Valdés Schwemm. "But putting it in mole 'hides' the slime texture and actually improves the sauce."

Slime and all, Valdés Schwemm is ready to convert people to enjoying the desert perennial through her nopalitos workshop Thursday at the Santa Cruz River Farmers Market (see accompany box for more information).

The free workshop is part of the 2013 Desert Harvester Series, which brings together local experts to highlight native foods that can go unnoticed.

"There is an awesome, thriving community of people who are huge advocates for native food," said Nadia Delgado, with the Community Food Bank of Southern Arizona. "They have taken it upon themselves to really research and explore the history and nutrients of the food that's all around and that we can take advantage of."

For the food bank, which sponsors the Santa Cruz River Farmers Market, hosting the Desert Harvester series was a natural fit with its goals of closing the hunger gap and helping people feed themselves, Delgado said.

Other workshops coming up will focus on mesquite harvesting, bean trees, verdolagas and prickly pear fruit.

"Prickly pear fruit is an easy sell - everyone loves it," Valdés Schwemm said. "It has a little bit of a sweet taste and a beautiful color."

Desert plants not only taste good and are readily available, they're also healthy.

"The amazing thing to me is how beneficial (desert plants) are to our health, especially for people with diabetes," Valdés Schwemm said. "They can be used to replace things in people's diets that aren't as healthy, such as using mesquite flour to make pancakes."

For Valdés Schwemm, the health benefits don't simply extend to the high fiber and nutrient content in the food, but also the unprocessed nature of the plants.

Even if it doesn't say it on the label, producers are allowed to use ingredients in processing food that you may not want to eat, Valdés Schwemm said.

"The food that you're collecting from your own yard or your own environment doesn't have these ingredients," she said.

Bagged shredded cheese, for example, contains a wood pulp called cellulose that while not harmful, isn't particularly beneficial.

Whether people are interested in eating healthier or trying new foods, the workshops are designed to set participants on the path to enjoying desert plants, organizers said.

How far they travel, and how slimy it gets, is up to them.
