these are so easy it's embarrassing.
I make these a lot because S and K like to take them for work / school lunches. I usually make bigger ones, but cut them smaller for the party so they'd go further. You can do them however you want. Also, note I put garlic in. That's not in the original recipe, so you can leave it out if you don't like garlic. To make them more interesting you can also throw in sundried tomatoes / fetta / whatever you want. But I'll just put it exactly as I made them for the party.
Usually I throw extra in so they aren't too bland, but knew kids were coming, and sometimes they like bland
4 sheets puff pastry (defrosted, just separate them and lay on bench for 20 mins)
1 box frozen spinach (defrosted - make sure you squeeze ALL the water out of the spinach or it will be awful)
1 tub ricotta cheese
1 tsp minced garlic
Sesame seeds (optional)
In a bowl mix together spinach, ricotta and garlic
Spread mix over pastry sheets
Roll up (from one side to the other)
Pinch in the ends with your fingers
Cut to desired size
Place on a baking tray covered with baking paper
Brush tops with milk (very important or the pastry doesn't crisp)
Sprinkle with sesame seeds, or with cheese, or whatever.
Bake in oven at 200 degrees c for 20 minutes or until pastry is golden brown and puffed up.
my note: it's so easy to get all the liquid out of frozen spinach with a salad spinner - no surprise i have the tupperware one lol
