Garden planning

I don't know about you, but I'm sick of spending $1 for a single red pepper in December. Seriously, it's a pepper. THIS has been the driving force for me to plan a garden for this summer. I have the space, I have a row of asparagus already, time to fill in some more. So far, I've mainly been researching, trying to decide what to grow, and not getting much of anything done. The list so far: Peppers kale (?) Zucchini Squash green beans (?) Potatoes (?)
