Potatoes and onions fry

This is an inspiration from Bengali cooking...but Ive changed the whole thing to suit my family's tastes... The original recipe uses poppy seeds and sugar and no masalas... and this is what I did...

Potatoes: 2 large
Onions: 1 large diced
Green chillies: 3 chopped
Turmeric Powder: 1/4 tsp
Garam Masala: 1/2 tsp
Salt: as required
Oil: 2 tbsp

Cook the whole potatoes till 3/4th done (I pressure cooked it on high flame for 8 minutes)
Peel the skin and cut into chunks
Heat oil in a kadai and saute the onions and green chillies till the onions turn slightly brown.
Add the turmeric powder, garam masala,salt and the potatoes and fry it.
Serve hot with plain rice or curd rice.
