I can't eat oven chips any more because they feel so fatty in my mouth.

- even the low fat ones!
I make my own oven chips or wedges - its dead easy, cheaper and a lot less calories - just chop up the spuds in to chip or wedge shape pieces, put them in to a bowl and stir in 1 teaspoon of oil (I use olive oil) and stir like mad with a wooden spoon until each bit has a very light coating, turn on to a hot baking tray, sprinkle with salt or seasoning (my favourite is mexican seasoning) and then bake until golden.
If you want to make it quicker you can microwave or boil them until they are half cooked before cutting them up.
Alternatively, if you've got the spray stuff, just lay 'em out on the baking sheet and spray them before sprinkling the seasoning on. Equally as nice.
