Add the lentils to the crockpot with whatever seasoning you like. I used oregano and bay leaf.
Add a can of tomato sauce, and an additional 1/2 can of filtered water.
Set on high for 6 hours. (after five I added in a cup of frozen peas)
I had a serving today and it made six additional servings. Portioning it out in these jars makes it so easy to grab a serving and heat it up.
I usually eat this within a few days, but if you want to, you can freeze it for another time. I wouldn’t freeze it in the canning jars, sometimes the freezing will cause them to burst.
