Okaaaay, that's cool and all, but what plants should I be investing in to make this happen?
I have a list for you, but, in general, what you are looking for are plants that can either be chopped and dropped frequently to build soil, or that drop their own leaves and stems and grow very quickly.
A lot of the plants on this list can actually be grown as riparian plants in the bog area of a pond, or otherwise, in areas of your food garden/edible landscape with poor drainage and flooding problems. These moist areas will help to lower the amount of watering you'll have to do because they hold water well already. These will also make excellent places to add coffee grounds and mulch as the additional moisture will help them break down more quickly and attract red wrigglers and earthworms.
The worms will begin nibbling on the plant waste and composting materials and naturally add worm castings to the area, which will hold even more moisture, which will then allow your plants to grow even faster. Your job is to get the snowball rolling and set it on a hill so it can grow as it rolls on down.
