Step 1

Mash 1 cup of the rinsed and drained black beans (this can be done with a fork, or pulse in a food processor; aim for a coarse mash, not mush).

Step 2

Place the mashed beans, remaining beans, tomatoes and chilies with their juices, and chili powder in a large saucepan set over medium-high heat.

Step 3

Bring to a boil; boil, stirring occasionally, for 3 minutes. Reduce heat to low and simmer, uncovered, for at least 20 minutes, stirring a few times. If the chili becomes too thick, add some water.

Step 4

Serve plain, or add any and all of your favorite toppings (see list of suggestions in the notes).
