Hello OP,
Suggestions for you to make some adjustments :
Breakfast.
Switch to a good quality bread - sourdough, wholemeal - 2 slices not 4 and have eggs one day, poached or scrambled and then change to it up to beans, mushrooms with garlic and parsley, tomatoes on toast etc ... personally I love a savoury breakfast.
What about porridge - good organic quality oats with frozen cherries, summer fruits, yoghurt, honey, chocolate nibs, walnuts, dates.
Brownies.
Make you own healthy brownies - you can do it!
Lunch.
Fish with Salad, Couscous
Snacks.
I would not have more bread but instead Nuts, Dates, Cheese, Fruit, Yoghurt.
Drink.
No cordial
Tea
Still Water
Dinner/Supper.
One pot dishes are really, really easy to do!
Take a look at Gemma Ogston on Instagram as she has some great recipes and does a One Pot Wednesday, she has two great cook books and also has a great brownie recipe too .... will find it and link.
Definitely more greens and protein OP ... you can do it!
Gemma Ogston is often on Saturday Kitchen (BBC) and she has a great Instagram profile with fab recipes.
