i wouldnt recommend anything without seeing what your current diet is like.
though im guessing a shake wouldnt be out of place post workout at the moment.
Here is what i tend to eat on average on a daily basis:
Breakfast: Weatabix with lots of milk or a nutri grain bar if im in a hurry
Lunch Time: Tuna and sweetcorn sandwhich with a nutri grain bar
Dinner: Ranges from, Chicken, pasta, chips , fish and potatos
Supper: Tuna and sweetcorn sandwhich and a choco bar. Protein bar after workout.
