What vegetables should I plant?

First, you should think of what vegetables you and your family usually love to eat. Then choose the most expensive from the list - perhaps red or yellow capsicums as they usually cost more than the green ones, mignonette lettuce as they are more expensive than good old ice berg etc. To keep your food interesting try different varieties of your favourites like Five Colour silverbeet instead of common Fordhook, or purple carrots instead of the more common orange (they actually turn orange when they are cooked).  Just because you are growing vegetables doesn't mean your diet has to be limited. There are literally hundreds of different varieties of every vegetable so you can have some fun with your garden as well as save some money.
