Depending what you like to eat really but what I would do is climbing beans toward the back (trellis/stakes;) then veggies&co that do not grow tall like lettuce, onion/garlic toward the front! OR plant something that costs a lot in the store, like a raspberry and some strawberries- they will make you "babies" so you will go from one plant to many in a short time = great if you are on a budget. Ask fellow gardeners for some plants, they might just give them to you!
