Greeting my Punjabi boyfriend’s family

ਸਤ ਸ੍ਰੀ ਅਕਾਲ! (Sat Sri Akal!)

In a few days I’ll probably have my first video call with my boyfriend’s family in Punjab. My boyfriend has already taught me a few simple phrases in Punjabi. He told me to keep it very natural and not too formal. For example, he suggested I simply say:

Sat Sri Akal Mammi Ji
Tusi theek ho?
Main theek haan

I was wondering if there is another short, warm and natural sentence that I could say. I don’t want to sound like I’m reading from a textbook, and I don’t want to sound too formal. I’d just like to make a good impression and show respect for his family.

What would a Punjabi daughter-in-law or girlfriend naturally say during a first video call?
