preheat the oven to 350
put all the spices and olive oil together in one smallish bowl and mix together thoroughly
slice off the peel of the squash and slice into circular discs, about 1/2 inch thick. scoop out the goop and seeds where necessary afterwards, keeping the circular shape
with your hands (hence my opting out of tumeric, but if you don't care or have gloves, about 2 tbsp would be the right ratio i think?) rub the spices and oil around each disc of squash
lay out on parchment paper on a baking tray
bake for about 45 minutes or until soft all the way through when poked with a fork
