The line may seem dope to someone with a basic education...
But he doesn't really explain what lasagna has to do with being a real "g"...It is just a bad simile, because lasagna doesn't move at all...It sits on the plate until its consumed...
Hip Hop is so full of bad similes...One reason I stopped paying attention to lyrics, and I just started focusing on delivery...I am enjoying hip hop more this way...
Jay Z had a better line in one of his songs, where he rapped "Murder is hard to digest"...That's how you right a dope bar..It is very subtle and makes SENSE which way you break it down...
Or 2Pac's "We can't get peace, until nikkas get a piece too" Dope bar...

You don't get this line? You need an explanation? You think the two have to be connected outside of the silent g?
