Step 1

Heat a large pan over medium heat and add olive oil and onions.  Cook for a few minutes, add garlic and cook another 30 seconds.

Step 2

Add the black beans and all the spices.  Mix well and roughly mash the beans with a potato masher or fork.  Slowly add in the reserved bean liquid until desired consistency is reached.  I used about 3/4 cup.  Mix well and cook until beans are heated through.

Step 3

Warm up corn tortillas on the stove and fill each with a big spoonful of black bean mixture and top with desired toppings.
