oO0Oo<<<^>>>oO0Oo Kitchen Garden oO0Oo<<<^>>>oO0Oo

This "garden" is probably the most accessable, the easiest, and "cheapest". It can be done wonderfully in a window with a wee few pots and a literal 
liberal handful of soil... oh, and some seeds, of course. (unless you can geat some starts from a friend... oh joy!) No need for toxic chemicals or 
gimmicky fertilizers, either. Literally let Nature take its course.

Then there is the outside kitchen garden, which can be realized either on a balcony or in the aforementioned "yard" (I am quoting that from here on out 
because a "yard" is a rather subjective and varied concept)

So, if you have a sunny window or a wide open walkway, place plenty of pots in, on and around them, and stuff those pots all full of herbs and other 
small veggie frens.

Above all... do not get discouraged if things go south. It's all a learning process. The important thing is that you are now paying attention to a wider 
section of your local "Nature"
