A chub is a packaging method, not a cut of beef. These log-shaped packages of ground beef are chubs. They come in various sizes.Actually it looks like a chub, possibly with some of the fat trimmed off.
For those who don't yet know, the chub is what they grind into ground meat. I have heard of people cooking them or parts of them and actually being quite pleased with the results. Why not really ?
At any rate, cut it. It serves no purpose that big. Cut the whole thing in half corner to corner. (looks a little square in the pic) See what's in the middle. Then maybe you'll figure the best thing to do with that thing.
