Good guess!
/ ___ ___ / ___ A ___ ___ / A / ___ A ___ A ___ I / I ___ / A / ___ A ___ A ___ ___ A / ___ ___ ___ /
(Note, I missed an I earlier. Sorry!)
Good guess!
/ ___ ___ / ___ A ___ ___ / A / ___ A ___ A ___ I / I ___ / A / ___ A ___ A ___ ___ A / ___ ___ ___ /
(Note, I missed an I earlier. Sorry!)
Is there an N there?
(This is a guess.
)
Yup.
/ ___ ___ / ___ A N ___ / A / ___ A ___ A ___ I / I ___ / A / ___ A ___ A ___ N A / ___ ___ ___ /
I guess T, please.
Bzzt! Strike one.
That was a tactical retreat. 
I would like to guess S now.
Two of them:
/ ___ ___ / ___ A N ___ / A / S A ___ A ___ I / I ___ / A / ___ A S A ___ N A / ___ ___ ___ /
Since other people seem to be busy doing something else, I’ll guess the next letter.
What about L?
Ding ding!
/ ___ ___ / ___ A N ___ / A / S A L A ___ I / I ___ / A / L A S A ___ N A / ___ ___ ___ /
M, perhaps?
The only time it’s not an even number. Weird…
/ ___ ___ / ___ A N ___ / A / S A L A M I / I ___ / A / L A S A ___ N A / ___ ___ ___ /
I guess I have to guess G. 
Nice!
/ G ___ / ___ A N G / A / S A L A M I / I M / A / L A S A G N A / ___ ___ G /
Note, forgot an M earlier. My apologies to @Monty, this is harder than I thought.
Wasn’t it bibliophage?
Guessing an “O”.
And I guess H. 
I’m not saying why.
It was, but Monty made some errors when he did his earlier.
Anyway, yes, two Os:
/ G O / ___ A N G / A / S A L A M I / I M / A / L A S A G N A / ___ O G /
You got it!
/ G O / H A N G / A / S A L A M I / I M / A / L A S A G N A / H O G /
Or,
Go hang a salami; I’m a lasagna hog!
Thank you. 
That was a little tricky because I didn’t know you can write the sentence without showing the apostrophes.
It was fun but I don’t have a sentence right now. Let me put my thinking hat on. 
Here is the new sentence:
/ ___ ___ ___ ___ / ___ ___ ___ ___ ___ / ___ ___ ___ ___ / ___ ___ ___ ___ / ___ ___ ___ ___ ___ ___ ___ / ___ ___ ___ ___ .
