Place your lentils in a medium sauce pot, add water, onion, and bay leaf. Bring to a low simmer and let cook for 20 minutes.
• Make sure you sort through the lentils looking for pebbles, and dirt, then give them a good rinse.
• You can leave the chile serrano whole or you can mince it and add it the vegetable mixture (it is spicier this way). •
You can make this in the instant pot as well (see post above for instructions)
