Yes, I was surprised to learn that variety satisfies me more so than volume, especially with lunches or snacks.
Having cheap veggie fillers in between "indulgent" bites leaves me feeling satisfied around 1-300 fewer calories vs. working my way through a single serving lunch. I'm sure it's mostly the mental satisfaction of having options but I also tend to take longer to eat when my meal is broken up into a variety.
I think the most important element was finding foods that excited me instead of just mimicking other snack bentos I saw. For example, marinating or pickling my hard boiled eggs with beets and onions appealed more to me than plain eggs. I didn't start finishing my almond portions until I started adding cayenne or powdered wasabi and spirulina to them, etc.
