Step 1

Heat oil in a large pot over medium-high until sizzling hot, about 1 minute.

Step 2

Add onion, garlic, and parsley and sauté until fragrant, about 2-3 minutes.

Step 3

Stir in lentils, oats, and turmeric until well mixed.

Step 4

Pour in vegetable stock and stir to combine. Bring to a boil, then reduce heat to low and simmer, stirring often, until the lentils and oats are fully cooked and the soup has thickened, about 20-25 minutes. Adjust the consistency by adding water or vegetable stock, as needed.

Step 5

Season with salt and pepper and a fresh squeeze of lemon, if desired. Serve immediately.
