There’s one sentence saying 「それと、忘れてた」. What does それと here mean?

P.S. I did search それと’s meaning in this
[https://www.weblio.jp/content/それと](https://www.weblio.jp/content/%E3%81%9D%E3%82%8C%E3%81%A8).
I still don’t get it.




`それと` is used to add a point to, usually, a list of other points previously
mentioned in the discussion.

Literally, it means `That, and`. `Also,` at the beginning of a sentence is
also a good match IMO.

In the 2) definition of the dictionary
[entry](https://www.weblio.jp/content/%E3%81%9D%E3%82%8C%E3%81%A8) you
referred to, it is mentioned that `あと` has a similar meaning. `あと、ハムもよろしく`
would have the same meaning. Or `そして` conveys the same meaning as well, in
case you'd be more familiar with any of these constructs.

As for the `[忘れ]{わすれ}てた`, the way it's written may be a bit confusing, but
remember it's a spoken conversation, and this is just a semantically
independent sentence "injected" in the middle of the other (as often happens
in oral speech). `それと、[忘れ]{わすれ}てた、ハムもよろしく。` is equivalent and maybe easier to
understand ? (remember that the use of punctuation marks is less strict in
Japanese than in, for example, English)  
The idea is the one of a dialogue: something like `That and -- I forgot, ham
too please.` or `Also, I forgot: ham as well please` in English.

Here the `それ` refers to whatever what previously mentioned.

You typically find `それと` in the context of "laundry lists": of requests, of
things to do or buy, etc.
