Peel and cut the vegetables.
Rinse the vegetables.
Dip it in Ice cold water for at least 30 minutes.
Now drain the water completely.
Pat the chips dry individually with a clean kitchen towel to remove any excess water.
Pre-Heat the oven at 180 deg C / 360 Deg F.
In the meantime in separate bowls add the cut potato, sweet potato, turnip, and carrot.
Now add a teaspoon of oil in each and salt to taste.
Coat them evenly.
In each bowl, one can either add black pepper or peri spice powder or just leave as is.
In a baking sheet, spread out the vegetables as evenly as possible.
Bake the vegables for 25-30 minutes turning in between.
Thick cut veggies will need more time.
Once you feel the chips are baked and getting brown, turn the heat on to 200 Deg C / 400 Deg F and broil the chips for the last 5 minutes.
Broil means you just keep the top rod on, it helps in getting the edges brown and crisp.
Once done, remove and serve it hot with Tomato Ketchup.
