Rinse the lentils and set them aside. Wash and shop all your veggies. In a pan over medium heat, add olive oil and cook the onion, carrots, and celery for a few minutes. Add garlic, oregano, salt, and pepper, and cook for one more minute.
Add the washed lentils to the pot with the vegetable broth and water. Turn the heat to high and bring everything to a boil. Once it starts boiling, lower the heat and let it simmer for about 15 minutes, or until the lentils and vegetables are nice and tender.
Turn off the heat and use a hand mixer to blend the soup until smooth. Taste and adjust the salt and pepper as needed.

This lentil vegetable soup thickens after refrigeration, but you can reheat it without adding extra liquid.
You can use chicken broth instead of vegetable broth, or even chicken or vegetable bouillon cubes.
Chopping vegetables into small pieces helps them cook faster, saving you time in the kitchen.
To make things easier next time, dice and freeze extra vegetables for quick homemade soup later.
