What should I bring when meeting my partner's family this christmas?

Hi! I (24F) need help bc my partner (23M) suggested na sailaha ko mag Christmas. Mag travel pa-Mati iyang parents and spend the holiday there, but he wants me to meet them first. We've been together for 5 years and i've only met his family briefly during our graduation (i insisted on meeting his family only when we graduated na so di ko maulaw na wa pakoy narating hahaha). So this time will probably be my first official meeting w them.

What food should I bring? Tho i atleast know how to present my self, some tips would still help me a lot.

Medj cowboy ako natawhan na family and my bf was raised in a conservative-ish fam so im pretty nervous hahaha. I really wanna make a great impression, coz most probably i'll see them for the rest of my life (hopefully). So please help me. Thanks in advance! ><
