Add NatLifts on Myfitnesspal and you can see how I eat over 3500 cals a day.
Each morning i will have a 800-1000 cal shake which can consist of 500ml milk, 2 scoops whey (50g), 2 bananas, 2 tbsp peanut butter and 250ml of icecream, although sometimes i leave the icecream.
Instant noodles (koka curry or beef flavour) + 200g cooked chicken breast is one of my favourites. - 740 cals
That or a £1 chicken fajita pizza from Iceland. Roll it up, takes about 5 minutes to eat.
