1)  Melt the lard in a large skillet.

2)  Add the onion and sauté, stirring frequently for 5 minutes
or until golden and soft.  Remove and discard onion.

3)  Add half of the beans with their cooking liquid and mash in the skillet with a potato masher.

4)  Gradually add the remaining beans and liquid and continue mashing to make a coarse puree until it begins to dry out.

5)  Transfer to a warm platter and sprinkle with Los Altos Queso Fresco Del Rancho or Queso Fresco Los Altos.

6)  Garnish with Los Altos Crema Mexicana Con Sal and tortilla chips.

Variation:
If you like the taste of onion, you can use finely chopped onion, in which
case do not discard.
