What will you bring for Thanksgiving?
Pyke, Pyth, Python 2, Foo, Brain****, GolfScript, Actually, &lt;&gt;&lt;, Gol&lt;&gt;&lt;, Seriously, Befunge, Fission, Haystack, 13 languages, 546 bytes
When I saw the other 10 11 12 language answer, I had to add an extra one two 3. I'm also seriously considering dropping Pyth if only to save on bytes. (at the moment 162 of them)

Pyke: Try it here! rolls
Relevent line of code:
#s[\g\r\a  \v\y)w.q)\r\o\l\l\ssp00/;oooooooo'stuffing;oooooo~'`turkey'

#s[\g\r\a  \v\y)w.q) - effectively a comment because # doesn't do anything with an empty stack
\r\o\l\l\ss - sum(&quot;r&quot;, &quot;o&quot;, &quot;l&quot;, &quot;l&quot;, &quot;s&quot;)
p - print(^)
00/ - raise a ZeroDivisionError to stop running code


Pyth: Try it here! gravy
Relevent line of code:
#s[\g\r\a  \v\y)w.q)\r\o\l\l\ssp00/;oooooooo'stuffing;oooooo~'`turkey'

#...) - while True:
s[\g\r\a  \v\y) - sum([&quot;g&quot;, &quot;r&quot;, &quot;a&quot;, &quot;v&quot;, &quot;y&quot;])
w - input()
.q - quit

All the )'s are for Pyth to make it compile without erroring on no input.

Python 2: corn
Line 1 is a whole comment
Line 2 prints &quot;corn&quot; and then has a comment
Line 3 has a string literal and then a comment
Line 4 onwards are comments

Foo: Try It Online! biscuits
Foo prints out anything enclosed in double quotes (&quot;). In this case I was careful to only include languages that could cope with other forms of string input (Special case for Befunge). If there was any text after the final &quot;, that would be printed too.

Brain****: Try It Online! salad
I copied the output of constant string generator. I had to escape all . characters with .q so it would play with Pyth and w. so it would play with Pyke. I added some extra - characters so the cells would get to the right points before printing at another . character in the 3rd line

GolfScript: Try It Online! cornbread
In GolfScript, # is a comment until end of line.
What GolfScript interpreter sees:
#comment
print'corn'#comment
'bread'#comment

In GolfScript, for whatever reason, print takes a string and prints it without a newline. Just having bread is enough to print it as well.

é - clears the stack of whatever junk was on it before.
'i'n'o'r'a+++++ - create string &quot;aroni&quot;

Of which are used:
;!+f'!n'!i'!s'!s'!e'!r'!d'L
                          L - start an atom going left
                      !d'   - create the character `d` and print it

Haystack (2015): PECANPIE (with EXTRA newlines!)
#\

 \25*8*0+c25*6*9+c25*6*7+c25*6*5+c25*7*8+c25*8*0+c25*7*3+c25*6*9+c

Of which do something functional:
  25*8*0+c25*6*9+c25*6*7+c25*6*5+c25*7*8+c25*8*0+c25*7*3+c25*6*9+c

I construct each upper case ascii codepoint for the letters in PECANPIE  in uppercase because they're all below 100. I then print them all out as characters.
