My favorite eggplant plate is from a text mex restaurant in Cambridge Ma. It's called Egplant Royale. Here's the description.
"Eggplant Royale
A bubbling-hot blend of cheeses, lump crabmeat and cajun spices, served over a delicately fried eggplant. this is a creole family tradition as served on royale street in new orleans' french quarter."
That place 2 doors down from the Sinclair? What you're describing has zero to do with Text-Mex, never gonna happen, but their menu was half Text-Mex and half Cajun (weird combination), so I could see it happening there. I ate their before meeting up with you, Rumborak, and the Queen. Cute Aussie bartender, and the shredded beef they put in the quesadilla was killer. My hunch is that they used chuck from their chili and shredded that.
edit: Holy shit, I nailed it! I rule!
Sadly, it looks like the place closed down permanently. The plague roughed them up pretty bad, and a fire finished them off.
