If you are cutting, it would actually be best not to use a protein shake after your workout and eat solid food instead since solid food is much more satiating then drinking your calories.
Post workout you are depleted of glycogen and amino acids from the strenuous workout you just performed. You want to eat a meal that is high in protein, high in quality carbs and low in fat. Adding in a good source of anti-oxidants is a really good idea to reduce the inflammation from your workout.
Something like
- lean fish or poultry for protein
- brown rice or a sweet potato for carbs
- broccoli or celery for fiber/antioxidants
