You’ll be hard pushed to go beyond too many calories if you stick with that sort of thing and water or zero cal drinks.
On goingly you need protein to feel full but for a crash diet that’s just about dropping pounds for the very short term just use the lowest calorie things to fill up. So piles of homemade coleslaw on a small potato, small chicken breast with tons of green beans. If you feel too hungry add half a baked potato or 1 cup cooked pasta and avoid fats and oils.
