The veg garden will definitely take up some of your time.... particularly if you have an area that is overgrown and needs to be "tamed" to be productive. To go along with the garden, you may want to build a compost pile to help with the fertilization of your new/renewed garden.
The garden will also help re-enforce your dietary choices..... fresh veggies are sooo much better than the stuff bought at the supermarket. You can pick the varieties of veg that you want, you can learn to hybridize your favorites and save the seed. That is a long term project in itself... since you wouldn't be able to see the results of the cross polinization until the following season.
good luck in your branching out! sounds like you have a whole new sets of adventure coming your way!
