What to do with grapefruit seeds?

I have several grapefruit trees and get tons of grapefruits almost year round. When I eat the grapefruits, which is fairly regular, I typically eat a good amount of the seeds with the fruit for nutrition, though I do get tired of them after a while.

Is there any recommendation as far as what to do with grapefruit seeds that might break the monotony of just eating them raw? Any way to prepare them or mix them into something... I've put them into smoothies which works fine, but I'm trying to see if there is anything more creative out there that I haven't considered.
