Add the beans, garlic, onion and water into the pot.
Turn the heat on to medium-high and allow the water to boil. Once boiling bring the heat down to medium-low, cover the pot, and allow it to cook for around 60 minutes.
After 60 minutes the beans should be soft. If not continue cooking until they are.
Once soft add salt to taste* and let it simmer for about 15 minutes.
We like serving them with a few squares of gouda cheese on top and a corn tortilla on the side.
Notes
*Set aside a portion for your baby before adding any salt.TO COOK IN AN INSTANT POT: add all the ingredients and pressure cook in high temperature for 30 minutes, let the steam release on its own for 15-20 min and just add salt to taste.
