In a Dutch oven, heat 3 tablespoons oil over medium heat and brown the onions, garlic and meat. Add salt, pepper, and turmeric, and sauté for 1 minute.
Pour in water—2½ cups/600ml for meat and 1½ cups/360ml for chicken. Bring to a boil. Cover and simmer over low heat for 1 hour for meat and 30 minutes for chicken.
