Cook your gnocchi according to package instructions. Make sure you salt the water well. They float to the top super quickly, so keep an eye on 'em. Drain and put in a bowl.
Squeeze your lemon wedge over the gnocchi.
Sprinkle parmesan on top, toss together.
Grilled chicken breast would make a great addition to this as well as white pepper. If you have extra calories that day you could make a low calorie alfredo sauce with the parmesan and fat free half and half.
