Just a quick note about what I just had for lunch because it was SO delicious. I would have some pictures but I didn't realise how good it was going to be until I'd eaten it all...
All you need is a tortilla wrap, some creme fraiche, vanilla extract and brown sugar, and a handful of blueberries (it would probably also be good with banana).
Place your wrap flat and imagine a horizontal line going through the middle. Put a big splodge of creme fraiche just above the line (without going anywhere near the edges) and drizzle a few drops of vanilla extract on top. Place your blueberries evenly over and then sprinkle with a generous amount of brown sugar. Roll up by folding the sides in and then rolling up. Now toast it! (I have one of those toastabag things which makes it super easy, but I'm sure it would be fine under the grill or done in a frying pan).
Good, right? Just be careful not to get the ooziness all over yourself like I did...
