The breakfast sounds yummy.
The part of the apricot seed I use is the small kernel inside the pit. I use a nut cracker to break open the pit and then grind the kernels in the coffee grinder along with pumpkin and flax seeds. Throw away the hard outer shell of the apricot pit or compost it. The kernels are what marzipam used to be made of when marzipam was real, and they have great anti-cancer properties.
Any kind of good non-dairy protein powder would work I suppose.
