Tea - chicken wrap with salad, small spag Bol, jacket with salad and tuna
Are you having all of those? I assume it's chicken wrap with salad OR small spag Bol OR jacket with salad and tuna?
Your lunch doesn't sound very filling, neither does your breakfast really. I'd be inclined to combine these to one, satisfying meal. Either a brunch / late breakfast or just lunch.
An example would be: big serving (half can of chickpeas) of hummous with a big selection from peppers, celery, cucumber, carrot. That would be around 250 calories and much more filling.
I'm also noticing carbs with two meals. I try to use carbs sparingly when looking to lose weight, aiming for only one (or none) meal having a carb portion. Of course you'll still getting carbs from your other foods - veg, fruit, dairy, pulses etc, so the carbs are still there. Just not over done.
Bolognese for example. I have just the bolognese sauce, no pasta. Or have the bolognese sauce with green veg instead of pasta. Your tuna salad, I'd just double (or treble) the size of the salad, have more tuna and skip the jacket potato.
