Peel the Bananas and cut them into thin slices, the thinner the better so that they get crunchy after frying.
In a bowl combine the Salt, Turmeric and Chill Powder and drag the banana slices all through the spice mix so that they are covered both sides with all the masala goodness.
Heat up a pan with the Oil and wait till it is hot. Once it has the desired temperature, take down the heat to a lower level and carefully slide in the banana chips, one batch at a time. Fry on both sides 2-3 mintues till they are golden brown.
Keep the cooked chips on a kitchen paper towel to get rid of excess oil.
You can store them in a airtight container a few days.
Notes
The Banana Chips cook very quickly, so be careful that they don't burn. Keep an eye on the cooking process.
