Wash your lentils then add to a pot with the water. Cook until the water is absorbed.
In a large pot, add avocado oil. After a minute add the onion, celery, and carrot and sauté until softened.
Add the cooked lentils, vegetable broth, tomato paste, thyme, oregano, and garlic powder to the pot. Stir to combine. If using fresh herbs rather than dried, make sure to finely chop them.
Bring the soup to a boil, then reduce the heat and let it simmer for 15-20 minutes.
Season the soup with salt and pepper to taste. Give it a taste, and add more herbs if desired. Optionally add fresh parsley to top. Enjoy immediately or store in an airtight container in the fridge and enjoy within 5 days.
