Here's a list of September's bounty! Buy locally!
Aubergine (Brits... Eggplant!)
Courgette (bah - Zucchini!)
I don't think you'd go hungry with that list.
NOW I am taking this list from an English website. But I don't think it will be too dissimilar here. Most importantly, you should buy these things locally! I'm really bad at this, but I want to start.
The hardest thing for me will be fitting in less tropical fruits in my morning smoothie, and more temperate in-season fruits. But, looking at that list, everything will be just fine.
