500 cals.. grab a big mac, no chips, no drink.
on a serious note. for dinner you should eat a well balanced meal rather than calorie counting beacuse your body is going to be using it all evening and all night to stay alive. take some lean meat, 2 or 3 different veggies, and some complex carbs. as for actuall suggestions, i like chicken fajitas. oven baked chicken peices, a low fat sause or seasoning, throw in some onion, salad, peppers shedder carrot or whatever, wrap in a wholemeal tortilla and away you go.
