Preheat oven to 400 degrees.
Wash and slice potatoes into even slices and put into a plastic freezer bag.
Add garlic flavored olive oil to potatoes in bag, seal and shake to disperse oil throughout potatoes.
Line a baking pan with aluminum foil and spray with non-stick cooking spray.
Place potatoes strips in single layer on pan.
Add salt and pepper to taste.
Add other spices that you wish. I like cilantro.
Place in preheated oven for 30-50 minutes, depending upon your desired level of doneness.
I checked an online dictionary- doneness: the condition of being cooked to the desired degree
Remove from oven, let sit for a few minutes, then enjoy!! And ketchup is not necessary!!!
