Make a plan first. Decide what you want to grow to eat. Ask a lot of questions. Simple things like 20 ft. of cucumbers near a fence so they can climb can feed several families over the course of the season. Your location says USA, that is pretty broad so any real advice needs to be zone specific to offer more tangible help.
There are a lot of vegetables out there and many different varieties of each. Some grow well in certain areas, some not so well. Check you growing zone map (can be found on the internet) to see when is the best time to plant certain things. A lot of vegetables do well until the summer heat hits and then they fade quickly or go to seed.
Things you could consider this time of year are tomatoes, beans, cucumbers, summer squash, bell and hot peppers, eggplants, swiss chard, etc.
Things like broccoli, cauliflower, Brussels sprouts are cool weather plants that will likely not produce much before the summer heat gets to them---at least in my neck of the US in New Orleans.
Best advice is start relatively small to see if this suits you. Lots of folks have grand plans but little follow-through and they lose interest, especially when it is hot and muggy and the garden could use a good weeding.
