Ok... they may not be the healthiest meal in the world. But they're terribly tasty and relatively easy to make, plus Hubby enjoys the leftovers in his lunchbox. They're basically a very plain sushi roll.
I simply make up a batch of sushi rice with my trusty rice cooker. (Don't waste your time or money on a cheap-o rice cooker. Spend the cash and buy a Zojirushi Rice Cooker and Warmer. It's totally worth the money.)
Then I take a sheet of toasted nori (sometimes I cut the sheet in half) and slather on the rice until it forms a thin layer. Sometimes I add veggies (like avocado) on top, other times I just leave it plain. I roll it up as I would a roll of sushi, then cut into pieces. That's it! Sometimes I cut one roll into two pieces and just eat it in bites like a hotdog.

I could make it healthier with short grain brown rice instead of white sushi rice... and sometimes I do. Nori is pretty healthy--it's a sea veggie--so I feel I'm at least getting my vegetables when I eat this snack. And if I use a filling like avocado or asparagus, I get a little nutritional boost, too.
