Aloo Karela Sabji (Potato & Bitter Gourd fry)

This happens to be a receipe from my grandmom, got this one from her during my U.S visit in 2006. A very simple recipe that tastes great with rotis. I love mine with Rasam and rice. I suggest using a non-stick pan for best results. I've posted this on demand for a friend who's been wanting this up on the blog for a while now. Enjoy Pritham and let me know how it turns out :O)
