Heat the oil, sauté the finely chopped ginger and onion in it for a few minutes.
Add the tomato paste and the Thai curry paste, if you want to eat less spicy, add 1 teaspoon and sauté too. Add the lentils and sauté briefly. Deglaze with the chunky tomatoes and one and a half to two times the amount of the vegetable stock. Let everything simmer for 20 minutes. Add the spring onion rings during the last 5 minutes. Season to taste with salt, pepper, agave syrup and, if you like, Pul Biber.
Serve on deep plates with a dollop of yogurt and chopped parsley or coriander.
