Preheat oven to 160°C fan.
Add flour and butter to a pot and melt together. Stir it well for about a minute.
Add the milk and turn the heat up full - MAKE SURE TO STIR FURIOUSLY - it won't work unless you are whisking all the time.
Once the mix starts to come to the boil turn it down to a medium heat. Allow to thicken for a minute or two.
Then add the wine, smoked paprika, chicken stock, smoked paprika and salt and pepper. Set that aside.
Parboil your veg for two to three minutes only. Then drain.
Add your chopped chicken to the base of your oven dish. Add the vegetables.
Pour the sauce on top generously. Add the breadcrumbs and cheese.
Bake for 25-30 minutes.
