According to the USDA Hardiness Zone Map, your zone is either zone 7b or 8a, depending on how far south you are. That's not terribly important for vegetable growing though because hardiness zones just indicate how cold it gets in winter. It doesn't tell you much of importance about the summer growing season.

There are 3 essential elements to vegetable gardening, a) light, b) moisture and c) weeding. There are many other elements, but those are the ones you must provide. Don't let anyone make this first attempt overly complicated for you. Although yield can be improved by many techniques, attending to those three basic needs will probably result in a satisfactory crop. Consider everthing else as "extra" and learn what else to do as you go along. Sure, feeding, mulching and soil improvement are excellent things to do and there is much to learn on those topics, but do those after you have provided the first three needs.

Much success to you!

That depends on what you are starting in your zone now.
If you want better answers you need to ask more specific questions.

Welcome to the delightful world of veggie garden. :-) Jim said it best ... don't let anyone overcomplicate it. Work with the basics and the easiest crops and then build on that.

Hello and good luck in growing your first veggie garden! The best place to start is to figure out what you and your family like to eat. For example: It doesn't make any sense to grow beets if no one will eat them. Make a list and then contact your local Cooperative extension to find out what varieties grow well in your area. Below is a site with great information about growing veggies.

Welcome! Enjoy your growing. You will find lots of good info here. If you can't find what you need, just ask. Someone will probably jump in with a helpful answer.

I'm starting my own first veggie garden this year. I went raised beds due to my soil conditions and JUST put my growing material in the beds today. If you want to read about my own trials and errors, just check out my blog. It's a light hearted look at my first year gardening. Learn from my mistakes and enjoy the fruits of your labor!

It would be helpfull for us to know just how big your garden space is. For example, peas take up a lot of space for what you get. However there will be a lot of time for another vegie in that space after pea harvest. The cool season crops will come off early also and maybe make room for something else.
