I'm eating this bento now and it's quite filling. According to my Weight Watchers scale, this bento clocks in at a whopping 4 points. And that's all from the salmon. I put the bento together in 3 minutes using carrot kinpira (recipe on justbento.com), preserved vegetables (daikon and ogo), romaine lettuce leaves, and a frozen salmon patty topped with furikake.
The only change I made in the kinpira recipe was to omit the sesame seeds and add a sprinkle of curry seasoning.
