No meal is going to really have the exact 40/20/40 ratio. Just preplan what you are going to eat the day before and prep it to eat. And every meal not having the 40/20/40 isnt a bad thing, as you want different nutrients at different times. Example: Many people believe in carb cutoffs after a certain time. Therefore you'd want a high protein/low carb meal than. Also, some people have about 80g carbs after the workout, but only around 30g protein.
