I think the idea of asking is great.
I would add that it would be best to stay with whole, natural foods as much as possible and avoid anything processed. Watch out for "hidden carbs & sugars" in many processed/bottled foods such as marinades, salad dressings etc. Best thing to do is read the label. Also, if you are having any fruit in your menu it is best to stick to berries (strawberries, blueberries, raspberries) and avoid things like pineapple, peaches etc. due to the high sugar content.
I would probably do a nice big salad full of gooddies and maybe some grilled chicken or I'd do up veggie kabobs and any type of meat kabobs.
Keep it simple.
