I've started hiding cabbage in everything. I mean, everything- whatever meal be it brekkie, lunch or dinner.
It doesn't taste of anything or affect the flavour of the meal, but it really bulks it out. Fills me up loads. I started substituting half of the amount of pasta I was cooking for white cabbage and other half never noticed! So then it made it's way into everything. Give it a go! (If you like cabbage)
