Wash hands with soap and water.

Drain the kidney beans, but save the liquid in a small bowl

Place the beans, vinegar, chili powder, and cumin in a blender. Blend until smooth. Add enough saved bean liquid to make the dip easy to spread.

Stir in the chopped onion and grated cheese.

Store in a tightly covered container and place in the fridge

Serve with raw vegetable sticks or crackers.

If you don’t have a blender, you can mix the first 4 ingredients in a medium bowl and mash with a fork. Then stir in the onion and cheese.
