Because it’s a non profit, meals are extremely cheap, only $12 including soup, salad, hot and cold tea, and of course the entree and several side dishes.
$12 for a meal isn't anywhere close to "extremely cheap".
If it was $4 for a meal, then the "extremely cheap" label would be appropriate. As it stands, $12 for a meal on a daily basis - prepared without any costly meat - leans more towards "absurdly expensive".
