Which herbs/spices go well with pumpkin and potato?

I suck at cooking. I'm currently boiling some pumpkin, white potatoes and sweet potato for lunch and idk what would taste nice with them? I'll be having some sort of veg too but I'm between two minds of either turning it into a soup with some chestnuts or keeping it as just veg...

Would really appreciate some help seeing as experience is often more useful than Google with this type of thing! Any suggestions? Thanks

(it's just for me so no worries if it goes badly. I'd just like to learn though)
