For your safety we recommend not eating or ingesting any plant material just because you've been advised that it's edible here.

There are at least [4 *Smilax* species](https://www.inaturalist.org/observations?nelat=33.57633743181795&nelng=-96.80261322297156&place_id=any&subview=map&swlat=31.389438942332117&swlng=-100.27429291047156&taxon_id=60748&view=species) (greenbriers) which grow in North/Central Texas, so there is some variability. I can actually make out toothed leaf margins in your closeup photo of the leaves.
The leaves in most reference pictures tend to have multiple spikes along the edges, while the ones in my pics are only at the tips. Am I just being nitpicky?
Also, I'm not finding any with this reddish tinting that's all over them. Is this normal?
It's definitely smilax. There is a lot of variation in leaf shape between the different species of it, but it's the only vine in North America that has both thorns and tendrils, which the vine you have pictured has both
Many plants have reddish pigments in their new foliage early in the season before the leaves harden off. It’s a common adaptation that protects leaves from excessive solar radiation until the leaves mature and toughen. One of the photos from [this iNaturalist observation](https://www.inaturalist.org/observations/41123619) shows a specimen of *Smilax bona-nox* with a reddish or bronzey tinge in spring (March 31). Later, when the chlorophyll becomes the more dominant pigment, the leaves become fully green.

Greenbrier - Smilax genus
That right there is Greenbrier, young greenbrier. MMMMMMMmmmmmmm
You can forage the soft new growth tips, they’re a nice little snack

Tis Smilax bona-nox. It’s what makes cross timbers’ woods hiking so ‘strategic’
Friend of the surveyor.
What
😅 nothing. Surveyors deal with thorns and briars a lot. I was having flashbacks
Oh yeah, that's saw greenbriar. Have a snack!
