Potato, green bean, kidney bean curry

Whenever my son announces he wants to cook dinner I'm delighted because I know we'll be having great food. He doesn't use recipes in a conventional way or measure ingredients, so it's usually hard to pin him down on just what he's added; but this time he was inspired by a recipe from one of my favorite Indian cookbooks, and I grilled him on what he did, so I could share his interpretation of the recipe.

He started with "Spiced Green Beans" from Lord Krishna's Cuisine: The Art of Indian Vegetarian Cooking by Yamuna Devi and David Baird." With this recipe as inspiration, he changed spices and added ingredients to come up with a truly delicious main course dish.
