Since you have your chicken & beef, I would go with grilled veggies, a beautiful green salad, and (apple) coleslaw. How about grilled asparagus, onions, portobellas, zukes, tomatoes with marinated artichoke hearts, etc., or a cucumber/onion/tomato salad. Saved a pic, but not the recipe, for a grilled & chilled veggie antipasti. You'll need something to wash it all down
- how about strawberry & white wine sangria. Dessert - fresh fruit, poundcake & ice cream.
