A Guessing Game

Last night, I tried something new and unusual, and I took a photo of this new and unusual dish.  Can you guess what's on this plate?  I will give you three clues:  1) It's fatty, 2) I ordered this plate at a Chinese restaurant, and 3) good luck finding the main ingredient in a big-box grocery store.
