These tacos are packed with savory barley and beans, and full of veggie goodness! What's great is they take very little hands-on time, since the filling cooks in a crockpot.
Combine all of the filling ingredients in a slow cooker. Cover and cook on low for 5-6 hours. Most of the liquid should be absorbed. Barley should be nice and tender and chewy. Hulled barley requires a longer cooker time. Pearled barley may be done in as little as 5 hours.
To make the avocado cream, combine all the ingredients in a blender or a food processor. Reduce the amount of chipotle in adobo by half or skip if sensitive to heat. Blend until well combined.
Make up tacos by spooning the filling into the tortilla. Top with some of the avocado cream and cilantro. Serve right away.
