Why don’t grocery stores in Houston have more ready to eat food options?

Midwest grocery chain won’t enter Texas market citing H-E-B dominance Being home for the holidays I’m reminded what I’m missing with the grocery stores in Houston. Why aren’t there more grocery stores that have a full deli with hot food? Publix, Hy-Vee, Albertsons and many more all have amazing delis where you can buy great food ready to eat in the store. Don’t get me wrong, I’m a big fan of HEB’s name brand stuff including their pre-made meals. But to me it seems like having a full food experience is standard in any other grocery store chain outside of Texas, and I don’t understand why HEB or Kroger doesn’t do this. I live in the loop in Houston so may just be that there aren’t any of these kind of grocery stores in my area, but even if that’s true that seems like a major opportunity in what’s likely the fourth biggest grocery market in the US.
