Cut Mango Curry

Sometimes raw mangoes turns soft and yellow, but tastes mixture of sweet and sourness, we can't eat them directctly nor use for cooking. Instead of throwing them away we can make a tasty side dish for rice. As today I thought to cook mango dal, but after looking at mangoes I shocked, as I bought them yesterday itself, but I felt happy that I can prepare this curry, which my mother used to cook like this with this sort of mangoes, it's a very easy n quick recipe with less ingredients.
