That second image looks like someone got their ‘nads cut off and then threw up.
To be fair, the public school I worked at (and still sub at) never had lunches that even remotely resembled the slop shown. The biggest changes to the menus in the last 8 years have been a switch to whole wheat hamburger/hot dog buns, whole wheat saltines (which are an affront to crackers everywhere), raw carrots & broccoli, dried cherries & cranberries offered as extras and the elimination of desserts that the kids and staff looked forward to (chocolate cake, cherry cobbler, to name two) once a week or so.
The portions were nearly always enough to fill one up.
The dirty little secret about the regulations covering school lunches is that the requirements are too onerous for most school districts to follow actually cooking, so they are forced to buy prepackaged meals from large distributors. To get lunches that are as small and ugly as those shown, I’ll bet somebody is getting rich on the side.
