OP, I have thought about starting this very thread a few times. Pizza, pasta, fishfingers, chicken fingers, check, check, check, check. You didn't mention sausages, some mistake surely? 
We also started with BLW, and the only way I could find to make it work was by having our main meal at lunch. In theory this was supposed to mean that DS and I both got a healthy, wholesome, balanced meal. In practice, it just means that I also survive on pizza, pasta, fishfingers...
DS goes on and off things, but I've found spag bol is reliable (he likes mushrooms, so I put a lot of them in), and also shepherd's pie. We also do an easy oven-cooked risotto (doubtless not authentic, but it's EASY) with mushrooms, tomatoes and plenty of parmesan. He does like his roasted veggies.
My favourite quick pasta meal is king prawns and tomatoes. Just quarter loads of tomatoes and cook them until a bit mushy, then add a bit of flavouring (I use garlic, black pepper and fennel seeds - which DS picks out) and the prawns, simmer for a couple of minutes and it's ready. DS loves prawns, so it's a winner in our house.
I found that DS was not keen on chicken breast, but will really go for chicken off the bone (i.e. leg), and ate a whole chicken thigh fillet that I put in a casserole the other day (with lots of sweet potato, tomatoes and mushrooms).
Hope some of these ideas might work for your DD. Let me know if you want anything more by way of recipe details.
