If you're looking for ways to use up the bushels of tomatoes coming in now, check out Russ Parsons' recent post on the LA Times' food blog. Along with a terrific recipe for gazpacho (that's very similar to my well-tested favorite), Parsons also posted a link to 30 other easy ways to enjoy tomatoes that will give you some terrific ideas!
While you've got the grill fired up for your "end of the summer" barbecue, consider throwing on some of the bounty of fresh, summer vegetables that are filling the harvest baskets right now. A grilled vegetable salad is a fantastic way to enjoy any combination of your summer harvests, and the black beans and a greek yogurt-based dressing add enough protein for this to be a satisfying main dish.
As an alternative to ubiquitous hummus dip, I really enjoy making baba ganoush. Roasted eggplant combines so well with the tahini, garlic, and lemon juice in this recipe to create a really terrific flavor. It makes a great sandwich or wrap spread, as well as just a quick snack out of the refrigerator that'll leave you feeling pleasantly full.
If the summer heat is getting to you and the last thing you want to do is turn on a stove, this is the recipe for you. Lovely zucchini ribbons make a great raw substitute to pasta, and when tossed with a lemon vinaigrette and goat cheese, it creates a perfect light dish.
