I don't like sugar in cornbread, so I guess in that way I'm more "southern".
I had some collard greens a few months ago, one of my favorite veges, at the cafeteria at work. They had sugar added to them. Grrrr. Sugar in greens? The time before that they were overloaded with salt.
I cook collards with some mustard and garlicky sausage, which add some salt but not too much. Sugar kills them, as far as I'm concerned.
Sounds like you're not having much luck at that cafeteria - judging by the bad taco bar experience, as well. Some establishments, imo, overuse salt or sugar for either lack of experience, or to mask the food for whatever the reasons - rather than enhance the dish/food. Have you considered making/taking your own lunch, etc. At least you know what you're getting, may be healthier, and less costly than eating out every day. I like this idea.
The video on Amazon made me chuckle.
