The Teppan (cooked on the grill in front of you) meal is not served in a monorail plate, it's served on the regular plate.
The "Okosama" meals (according to the Allears menu) are the ones that come on the monorail plate and they are cooked in the kitchen.
I posted a couple of pics on the "Disney Food Pictures Part III" thread, page 120, post 1789. It's not a great example, but it's my 7-yo eating the kids' Chicken Teppan meal. He had chicken (obviously, lol), rice, udon noodles, and the veggies.
