Heat avocado oil in a saucepan over medium heat. Once oil is hot, add chopped onion and cook, stirring occasionally, for about 5 minutes. Add spices, tomato paste, and garlic. Stir to combine and let cook for 1 minute.
Add in broth, water, and lentil. Bring just to a boil then reduce to a steady simmer and let cook, stirring occasionally, until lentils are soft and beginning to break down a bit; about 15-20 minutes.
While lentils are cooking, heat two tablespoons of olive oil over low heat. Once hot, remove from heat and stir in dried mint and aleppo pepper. Set aside until ready to serve.
Using a sturdy whisk, whisk lentils thoroughly to break the soup down to a bit of a chunky puree. Add a splash of white wine vinegar and season with salt and pepper, to taste.
Serve soup with a drizzle of spiced oil and a sprinkle of chopped parsley.
