The Sainsbo's ready rolled fresh stuff is excellent too. The puff pastry is brilliant for making tarts topped with whatever you fancy - they look and taste fantastic for virtually no effort. What are pizza pasties?
I use a jar of bruschetta mix (I was given one for Christmas, and found it locally since - great shortcut!!) on top of puff pastry, and a bag of mini mozarella balls (torn in half) scattered over the top to make a nice tart for some nights the au pair (veggie) is eating with us. Throw a handful of rocket (dressed in balsamic vinegar and olive oil if feeling really poncy) on top and it is quite delish!!
I mostly used to use the frozen slab and roll it myself - now I usually keep a frozen for emergencies, but use fresh slab or ready rolled, and they are great.
Jus rol also do the croissants in a tin (have always had those as treats since we were small). But now also do Pain au chocolat in a tin and do a pizza kit that is 2 pizza bases (2 tins) with a jar of pizza sauce for easy pizza night (just need cheese and toppings, and DD likes margarita so no toppings needed some nights).
