This is from Real Simple October 2010.
1 pound fresh chorizo or Italian sausage, casings removed (Super Saver sells chorizo in 1 lb bags by the deli section)
1 russet potato (8 oz), cut into 1/4-inch pieces (really, four potatoes is better)
1 15oz can black beans, rinsed
4 radishes, cut into small pieces
1/2 cup chopped fresh cilantro
2 T fresh lime juice
1 T. olive oil
1/2 t ground cumin
Kosher salt and black pepper
8 hard taco shells, warmed
1 avocado, sliced
1/4 cup sour cream
In a large nonstick skillet, cook the chorizo and potato over medium-high heat, breaking up the chorizo with a spoon, until it is browned and the potatoes are tender, 12 to 15 minutes.
Meanwhile, in a medium bowl, combine the beans, radishes, cilantro, lime juice, oil, cumin, 1/2 t salt, and 1/4 t pepper.
Fill the taco shells with the chorizo mixture, black bean salsa, avocado, and sour cream.
*Honestly, we did not make the salsa. I had a black bean salsa in the pantry to use. We put the chorizo potato filling topped with rinsed black beans, salsa, sour cream and cheddar cheese. They were really good.
