When doing split workouts the ideal is cardio in the morning on an empty stomach.
Your first meal (after cardio) shouldn't be any different than if you didn't do cardio.
Typically a balance of moderate proportions of carbs and protein, or, if you're on
a low carb diet, your usually low carb breakfast.
In meals after your weight workouts it's more critical to ensure you have lots of carbs.
You should consume 40-50% of your daily carbs within 90 minutes of your weight workout.
Your post workout 'meal' should be at the gym - try a shake with a couple scoops MRP and some high GI carbs, such as a banana, raisens, dates etc.
In the next 1 to 1.5 hours have a large meal with both carbs and protein.
