Yes. Jersey.
Down south, it is difficult to get a salad.  It like croutons cheese and a little lettuce. Lol.
They don’t eat much green veggies either.  We like Cracker Barrel

You must have gone to the wrong restaurants down here.  It's as easy to get a salad here, as anywhere else.  What makes a "good" salad for you?

And as for green vegetables, there are the various forms of greens, mustard, collard, turnip, and so on, really very good, at their best when bacon is added.  In Kentucky (which is at best pseudo-Southern, unless you get way down in the state south of Paducah and Bowling Green perhaps), a meal without green beans is barely even considered a meal.  (Strangely enough, this holds true to a very large extent in France as well, they serve haricots verts with everything.)  And then there's okra, which is kind of an acquired taste, I like it, but it doesn't like me, or rather, it doesn't like my kiszkas.  Southern fruit pies are legendary, FWIW, I'm baking a cherry pie, largely from scratch, right this very moment.  And Louisiana, the one Southern state I haven't visited, triste à dire, is a culinary world unto itself.

Cracker Barrel's breakfast casserole is one of the seven wonders of the world.

Be very watchful of your young people. Not to scare  you but beware.  Our home schooled daughter, age 18, in 1994 went to work at a Mcdonalds.  The employer told us that she was the only teen that didn't smoke and we were proud.  

Come to find out later, the smoking teens were smoking to hold them off til they could get to the drugs.  Sorry to say our daughter went their way. At age 20, had a child out of wed lock. At age 36 died of over dose to wine and ibroprophen (sp).  Very very sad.She was going to school to be a nurse.  very sad, we prayed so hard, many tears and still pray with hope.

Tennessee in the Gatlinburg area it can be difficult to get a good basic salad without tons of cheese and bacon bits.  I need onions in my salad too. Okra is good.  In Virginia, Pink Cadillac diner has a really good salad with steak strips. Yum.

You have to be careful on Friday’s because they put bacon bits in salad at Cracker Barrel   Lol.

I would like to visit Louisiana.

Well, that much probably goes without saying, Southern Appalachia is known for its hearty, simple food.  Pinto beans and cornbread are the national dish.  I wouldn't expect to get a wimpy salad in Gatlinburg (massive tourist trap).  Bob Evans, roots in far southern Appalachian Ohio, is the gold standard for biscuits and gravy, but many of them have closed down.  They started out as a country breakfast-intensive restaurant, then started expanding their menu, to the point that they don't seem to know what they really are anymore.  Shoney's, with West Virginia origins, made the same mistake, they're a shadow of what they used to be, their spaghetti with meat sauce and garlic bread was awesome, but now they commit the apostasy of baking it in a dish.  Took something perfect and royally butchered it.  (Kind of like trying to replace the TLM with the Novus Ordo.)  But their Slim Jim sandwich (thick sliced ham with cheese and special sauce) is as good as it ever was.

There is no concept of Friday abstinence in the South outside of Louisiana, not even during Lent.  There just aren't enough Catholics.  They have no idea what you're talking about.   In a religious culture where "Jesus paid it all", penance is an unknown concept, as is "growth in holiness" --- once you "get saved", that's considered an irrevocable decision that makes all things right, from that point forward, until the day you die.  Some might admit biblically-derived fasting, but it's very uncommon.
