I just made these Yammie Chips.. Organic self picked potatoes straight from Mother Earth :) ! I used 3 organic Potatoes. Sliced thin with knife. Sweet potato/ White Sweet potato - I just peeled them with a normal potato peeler.
Used half a medium Orange sweet potato.
1 small white sweet potato.
1 tsp olive oil on the potatoes. Spices - Chili - Garlic - Salt - Pepper - & a little sprinkle of Parmesan on them the last 10 min.
I baked the "Normal" ones first. 10 min 200c - turn around 10 more minutes. So crunchy ! A source to Potassium as well :D (you don't need to flip the sweets)
Then i got so exited i just peeled sweet potatoes and threw them in the oven too at 175 degrees for 15 min :) Spiced them with same as above (Not Parmesan)
God i really hope someone else will try this out! so easy.. And a much more healthier alternative. (Nutrient Geek)
Here are all finished together - ready to be eaten with 
It may seem that they aren't done after 15-20 minutes. but they just need to cool down a bit :)
enjoy i know i WILL ;)
