Peel and wash the brown onion.
Add the raw lentils and approximately a cup of water in the pot. Make sure the water barely covers the lentils. Turn the heat on.
Turn the heat off a minute after the lentils start boiling.
Sieve the lentils to remove the water. Put the lentils back in the pot.
Add the peeled onion and the rest of the igredients (except from the olive oil and the vinegar) in the pot and mix.
Heat 4 cups of water in the water boiler. Poor the boiling water in the pot and mix.
Turn the heat on. Since the carrots are frozen and some igredients are at room temperature, the water will stop boiling.
When the water in the food starts boiling again, reduce the heat and cover the pot completely with the vented lid.
Make sure the water is still boiling after reducing the heat.
After 30 minutes, stir to check there is still enough water in the pot. Since every stove is different, it is possible that slightly more water will be need to prevent the food sticking to the bottom.
Keep cheking (every 5-10 minutes) if there is still enough water for 20 more minutes.
Turn the heat off and remove the pot from the stove. Remove the onion and the bay leaves.
Let the food rest for 5 minutes. Serve and add a tablespoon of olive oil and a teaspoon of apple cider vinegar. Enjoy!
