I am also a fan of Cookpad Japan (http://cookpad.com/). I love to use it to find recipes for a particular ingredient (much like I use EYB). One time, I had some extra shirasu and looked for some ideas on how to use it and found this recipe (http://cookpad.com/recipe/2137577). It couldn't be simpler and makes a quick, tasty lunch/snack.
Thanks for mentioning the Spanish version (https://cookpad.com/es), I will check it out.
