I make rice "sandwiches" using a cypress sushi mold with plastic wrap and short grain, sushi rice. I layer bacon lardons or canned salmon, furikake, and toasted sesame seeds between rice strata. I tend to wrap the compressed rice in nori sheets, which helps hold it all together, like onigiri. I wind up with two sandwiches, roughly 3"x3" for off bike or four strips if I intend to nosh while riding.
