As I understand it, your meals are:

B: granola
S: nectarine
L: salad
D: salad or veggie with protein

You could modify it to something like:

B: granola, 2 eggs or a yogurt (not a high sugar one)
S: nectarine, handful of nuts (almonds, walnuts or pistachios)
L: salad
D: salad or veggie with protein

This would bump you up by an extra 200-300 cals per day.
