Add red wine vinegar and use a rubber spatula to deglaze the bottom of the pot for about 5 minutes.
Once the red wine vinegar is evaporated, add the lentils, peas, vegetable broth, and coconut milk. Bring to a simmer and cover for 1 hour and 45 minutes, lifting the lid to stir every 7-10 minutes to ensure the soup does not burn to the bottom.
At some point you will need to add 1-2 cups of water to ensure the yellow split peas continue to absorb liquid to and cook.
Once the soup is fully cooked, add the nutritional yeast, herbes de provence, onion powder, salt and pepper
