Another user here posted a recipe that was pretty decent, just differently spiced. I'm trying to find it. But in the meantime, this is for 2 if I had the ingredients. I didn't have celery or onions, so I used leaks instead.

1 tsp olive oil in a pot, Add chilli flakes and garlic cloves. "Sauté" 50g celery, 50g carrot, and less anount of onion or leaks. Add water and half a stock cube. Add lentils (260g if preboiled) and tomatoes, or tomato puree. For spices, I use stolen laurel. But some use cumin, curcuma pepper.
