Yup, Rick's last point about the tomatoes is what I was going to start with. We really need to know what part of TX you live in, Debbie. The climate is vastly different there, from the Gulf Coast all the way up to the panhandle.
Here in FL I am just planting all my veggies to grow over the winter. I'll have tomatoes to eat and share starting maybe as soon as late next month, but for sure in January and February. But my tomato plants will definitely be dead as doornails by June.
Lots of the cool season things like salad greens and cabbage relatives will grow straight through our coldest winter weather here. So if you're in somewhere like Corpus Christi or Houston, you could start right away.
Oh and by the way, the title of your thread 'best sun for veg garden' - is that a question? If so, the answer is "full sun, all day" if you've got a place like that. Veg's work pretty hard to produce good stuff for you to eat, and they need all the solar energy you can find for them.
