I have a full fat natural Greek yogurt with a few berries thrown in for breakfast, and a mug of tea with a dash of milk.
Lunch I may have one slice of toast (wholemeal heavily seeded) and butter with poached eggs, or a tinned salmon salad with cherry toms, cheddar cheese, real mayo and a slice of the same bread and butter, or bacon, eggs, toms and mushrooms with a slice of the same bread and butter, or egg mayo (2 eggs and real mayo) with cherry toms and a slice of bread and butter.. I can manage 1 slice of this bread without spiking unduly.
Evening meal is normally meat or fish with some veg (not a veg lover), plus mushrooms, toms and a very small portion of spuds - 2 small ones at most. Sundays we always have a proper roast dinner with chicken or lamb, cauliflower, other veggies, and 2 small roast spuds.
I drink several mugs of tea throughout the day and vast amounts of cold water. A glass of red wine about 4 evenings a week.
I never snack and haven't got a sweet tooth so don't bother with puddings, maybe the odd handful of berries.
