I’ll give it to Jack that plain white rice doesn’t have much flavor (even high quality rices right out of a Zojirushi rice cooker).
But I’ll be dammned if it isn’t enjoyable and satisfying to eat with a little bit of Furikake or ponzu, let alone some nice gud meats and begidables. (I could eat Braised pork and sticky rice

with a touch of Gowrlick Chili crisp for a month and never get sick of it)
That’s like calling pasta a filler. Even fresh plain linguini noodles with nothing on them taste like the back of my hand. But a little dash of butter and freshly ground black pepper at the minimum can really do wonders. Let alone an egg, oil, and panchetta. But Jack needs a bunch of bacon up, 2.2lbs of undrained hamborgl, half a bottle of HFCS laden ketcha, and sawdust cheese to make pasta (or rice) edible. And even then he would bitch that it’s a poverty failure dish and not the $3 goyslop breadstick subway “dippers” or Bk tendiewraps he forces Tammy to eat at the goyslop stores on JOTG.
Jack’s food insecurity is on full display every time rice comes up. Boomers raised on con Agra food pyramids, who are children of depression era parents all sperg out if there isn’t a hunk of gud meats or too many bones to assure them they got their dollar’s worth.
Jack doesn't merely claim to be healthy - He boasts that the health of each and every able-bodied patron he scoots around in Walmart is inferior to his own; and he sneers in obvious contempt whenever he observes them picking out produce from his EZ-Shopper. He is also much smarter than the rest of us; thanks to his surplus of "common sense" and ear finely attuned to detect wokeness.
I’m honestly surprised that we don’t see Jack wearing variations of those white trash “I
hate stupid people” t-shirts. And not the ironic “born to shit, forced to wipe” ones. Instead we get the same colorblock grey/black/dandruff, grey/red/dandruff, NYC, or his beastie boys shirt that he’s been farting in for the last 6-7 years
