What's the healthiest thing you can spread on a cracker?

I always make my own tahini too, it's so much fresher. Just about anyplace has the Arrowhead Mills brand 12-oz bags of sesame seeds, and all you have to do is whir them in a blender for a couple minutes (the mini-blender attachment for a stick blender is perfect for this) - it won't be as smooth as commercial tahini, but once I put it in a recipe I never notice the difference.

A regular blender will do this!?! Cool! I love it, but don't use it all that often - making just what I need and to have it fresh as well would be best. Do you add any liquid or oil to the sesame seeds before you blend them?
