Attempted to increase protein to feel fuller. Am i doing it right?

I posted the other day to query why I was hungry when I was eating plenty. I got plenty of good advice from people. I have been playing around with my planner to try and fit in more protein and fat, without going over my calorie allowance. So, im really after some feedback on whether I have done it in a healthy way that should keep me fuller?

I have increased my liquid intake. Reduced caffeine. No fizzy drinks.

Changed my breakfast from porridge, to 2 slices toast with mushroom pate, a boiled egg, and a Danio yoghurt (high protein fat free)

Snack, I still have fruit, but I have swapped my Sunbite crisps to 25g of mixed seeds or nuts.

Lunch, still having homemade soup with pumpkin seen ryvita, with a piece of fruit, but find the soup filling and easy. I'm trying some recipes that have meat in next week. Sometimes have a slice of ham or some cheddar with it. Plus an Actimel Probiotic drink.

Snack, still give in to 2 Jaffa cakes with a cup of tea when I get in from work, to unwind before anyone gets in.

Dinner, my dinners were fine. Always included protein, brown rice, brown past or sweet potato and plenty of veg. Usually homemade curries etc. However, we are having pizza tonight, but I have chosen a thin based chicken Pizza Express pizza, that I will only have half of with salad (about 400 cals).

I really want to come up with foods that I can throw together for breakfast and lunch midweek that are healthy, easy and yummy. Otherwise, I know I wont stick to it, as at the moment it's driving me slightly crazy.
