Step 1

To make the black beans: We’re going to use the cooking liquid from one can of beans (or substitute 1/3 cup water for the cooking liquid). Rinse and drain the other can of beans. Once the beans are ready to go, warm the olive oil in small saucepan over medium-low heat. Add the cumin, garlic and salt. Cook, stirring often, until fragrant, about 30 seconds to 1 minute.

Step 2

Pour in the can of beans with all of its liquid (or 1/3 cup water). Stir to combine. Mash up a portion of the beans with a potato masher or serving fork. Cook for a few minutes, stirring often, until the mixture reaches a simmer. Mash up the beans once more, then add the rinsed and drained beans.

Step 3

Stir to combine. Simmer for a few minutes, then reduce the heat to a bare minimum while we finish the remaining ingredients. Cover the pot, and stir it every few minutes so the beans don’t stick to the bottom of the pan.

Step 4

To make the “crema”: Combine the yogurt, lime juice and salt in a small bowl. Stir to combine. If desired, add hot sauce, to taste. Set aside.

Step 5

Warm the tortillas in a large skillet over medium heat in batches, flipping to warm each side. Alternatively, you can warm them directly over a low flame on a gas range. Stack the warmed tortillas on a plate and cover with a tea towel to keep warm.

Step 6

Soften the cabbage just a bit by sprinkling it with a couple dashes of salt. Then use your hands to “massage” it by scrunching up handfuls of cabbage until it is slightly wilted and fragrant.

Step 7

Finally, assemble your tacos: Spread a layer of beans down the center of each tortilla, followed by a small handful of cabbage, a generous drizzle of sauce, and sprinkles of cheese and cilantro and/or green onion. Serve immediately.
