Throw them in a plastic bowl and add a teaspoon or two oil and mix them well so everything is coated. If you going to cook the whole packet just add oil to packet and have one less thing to clean.
If you want slap chips then cook the lower heat and longer, maybe 170deg for 15min.
If you want it more crispy chips, higher heat, say 190 for 10-15 min. They are thicker than the normal chips so takes a bit longer of you want them nice and crispy. Open every 5min and toss them around a bit. And after 10m min have a look how they are and decide if a bit longer is needed.
This is the slap tjips, I did not add oil and cooked crispy. about 12min
