You could do another lean protein, or a serving of yogurt or some fresh vegetables. If I were you, I would do the lean protein. When I don't do protein late in the day, I wake up in the night wanting something or am famished the next morning.
Naturally there are some days that are easier for me. On days like those, I clip my coupon and say a prayer of thanks. God knows there are way too many OTHER days--when I cannot stop eating.

That being said, plenty will come behind me talking about what your daily calorie needs are and yada, yada. Zig Zag dieting works wonders for me though. Lately I have had way too many ZIG days!
