Afghan Sauteed Pumpkin (Kadu Bouranee)

In a large pan, heat the oil. Add onion and cook for about 5 minutes, until golden. Add garlic, turmeric, ginger, sugar, salt, pepper and cook, stirring, for 1 minute more.

Add the tomatoes and water, and bring to a boil. Add pumpkin and stir. Lower the heat and cook, covered, for about 30 minutes, until pumpkin is tender but firm. Check from time to time if there is enough liquid, and add more if needed.

For the sauce, mix together the yogurt, garlic, and salt. Serve the sauteed pumpkin with the sauce on top. Garnish with mint.
