Do you enjoy your meal? vs Are you enjoying your meal?

[Psalm23]

Greetings to all my friends.

I am a new member here. Actually, I sign this up in the hope that I can help me wife to improve her Engish. She is attending English classes and quite often she ask me some questions which I couldn't answer. I hope you all can help me.

One question for now:

When do we use DO and when do we use ARE?

For example:

Do you enjoy your meal?
versus
Are you enjoying your meal?

Which one is correct and when to use them?

thank you for all your help.

I would normally ask my friend " Did you enjoy your meal? " after I have a meal with my him/her.
I would normally ask my frined "Are you enjoying your meal?" when I am having a meal with him/her.
I don't know if I would ever use "Do you enjoy your meal?".
