This is yummy as taco filling or served as a side dish with a dollop of Greek yogurt on top.
Do not use unhulled (orange) lentils or they will turn into mush.
Put in a slow cooker:
(The baking soda is to neutralize the acid in the salsa, so the lentils will cook better.)
Cook on high 2 hours. Then switch to low until it is time to eat.
Fluff with a fork. Remove bay leaf.
