Ideas for other meals: griddled chicken breasts with LOADS of veg.
A nice tuna steak ditto with the veg.
Or even a nice steak steak! (be sure to cut off the fat)
Cauliflower cheese with the cheese sauce made with cornflour rather than butter and flour, and use extra strong cheddar so you lose less.
Or simply SMALLER portions of what you usually have (provided they are not loaded with cream etc!)
For lunch I have a tub of rocket salad, with radishes, cherry tomatoes and a boiled egg (if I've remembered to cook one). Plus some fruit.
If you're at home, why not have an omelette? (I take the veiw that eggs are good for you, unless you are binging elsewhere). Put some peas in it to make it extra healthy.
I make sure to have a minimum of 5 items of fruit or veg a day. That helps fill me up.
I also have a few nuts when I get in in the evening - that seems to take the craving for a snack away - although if I really want it, I allow mu=yslef one square of 70% chocolate a day (actually NOT that calorific, and solves my chocolate craving!)
None of this is weightwatchers stuff - I'm just trying to eat sensibly and healthily and stop myself from snacking.
