In Germany, individual plug-in panels sell for as low as 200 euros, or about $217, at big box stores. Complete sets, including mountings, an inverter and cables, are about twice that cost.

You can debone chicken without turning it into pink slime.
I’d rather expect it to be made from another part of the chicken in the style of wings.
