It doesn't seem too bad, although I'd become less reliant on the protein shakes. You could have one with Breakfast and one after workouts, but the third of the day could be swapped, because there are other options for Protein like Low Fat Cheese, Peanuts, Chicken, Beef, Turkey, Ham, Boiled Eggs, Meat based Microwavable soups, Microwavable Rice dishes, Microwavable Baked Beans etc, so plenty of options.
Just make sure with some of those to factor in the Carb content, as some have it and then add a carb source in, in an appropriate way if needs be.
Careful on the Tuna too, as it's the heavy metal content that should be heeded. I'd limit to 3 portions a week, as per current guidelines.
