I eat about 0.5-1kg of cheese each week. I would suggest you include it as a protein source. But its up to your taste preferences. (diversity yo!)

A hard boiled egg might suit your salad.

you can probably try to find pre-roasted oats/museli (sometimes with the nut mix already created. (at extra cost but also tastyness)

A very quick and filling food for me is peanut butter and cellery. (although it depends if that is even remotely normal where you come from)

Also snap-peas, about a bowl full, boil water, pour over peas, sit for 1minute, eat peas, wait 5, drink water. mmmm..

your diet plan lacks rewardy-snacks. for any time you feel like "I did a good job and want to eat something fancier" (read: chocolate, dried fruit)
