Help with Kerala cuisine

My gf is mallu. She misses her home (Kollam) I make her food since I got time,it's my love language. She mentioned my cooking is like "men's cooking". Idk what's that supposed to mean but I feel I cook decent? Anyway, she misses her home a lot and maybe I can try to make something she misses a little more " Non male" Or more authentic to her local cuisine.She eats "putta" (I hope I wrote that right) orders biryani from outside. I'm north indian ( if that matters) and a good chunk of my diet is vegan but I cook her non veg as well and often but since both of us work we both don't have time.

Any tips, suggestions?
