Add the two tablespoons of olive oil to a skillet over medium to low heat.
Once heated, stir in the garlic, onion, carrots, celery and white wine vinegar.
Add a splash of water if there is not enough liquid in the pot. Sauté the onions and garlic until they become soft and translucent.
After a few minutes, add in the vegetable stock, bay leaf, lentils, salt and thyme.
Let it simmer in a covered pot, stirring every so often, to allow the mixture to absorb the vegetable broth. After about 25-30 minutes or until the vegetable broth has absorbed into the lentils, turn off the heat. The time may vary depending on the size of the lentils.
Remove the bay leaf and any fresh thyme sprigs from the lentils.
Add the lentil mixture into a serving bowl.
Add more salt, black pepper or other spices as desired. Serve warm!
