LH, I am confident I have found your ideal, fast food restaurant:
L&L Hawaiian Barbeque. (Locations in Renton, Federal Way and Lakewood.) Order the BBQ Mix Plate. If, after consuming the entire serving, you are still hungry, you have tapeworm or more dire issues. This truly is food served by the pound in portions that would make Claimjumper blush. (And, as fast food goes, really not all that bad.) One serving could support a family in India for a week. Chowdown LH!
