Begin by finely chopping the onion and garlic.
In a skillet, heat some lard or neutral oil over medium heat.
Add the chopped onion and garlic to the skillet, sautéing until they become soft and fragrant.
Stir in the chipotle en adobo, mixing well with the onion and garlic.
Next, add the cooked beans along with the beans juice or stock to the skillet.
Mash the beans with a fork or potato masher to your desired consistency.
Season with salt to taste, and continue to cook until heated through and slightly thickened.
