I want it to be very lean.

John, can you do me a favor? Can you help me cut this chicken?

At your service. How do you want me to cut it?

I would like half of it cut into slices, and the other half diced.

OK. Half sliced and the other half diced.

Oh, by the way, I want it to be very, very lean. Not even a shred of fat.

Got'cha. Cut off the fat.
