In my experience "Samboosa" can be a pastry dough stuffed with just about anything.
You can use an egg roll wrapper, Pillsbury refrigerated pizza crust or an all purpose pastry dough.
What ya need
the dough you with to use, here I am going to use the APPD.
1 1/2 cups of drained frozen spinach.
1 cup of a soft Arab style fetta cheese like Green Land or Panda. If you cant find it than use the fetta you can find.
1/8 a cup of real shredded Parm. and Romano cheese.
salt to taste
a dash of ground red pepper.
1 egg white well beaten and set to the side.
What ya do.
In a medium sized bowl mix your cheeses and spinach up add seasoning and set to the side.
get your dough rolled out and cut into rounds if you're fancy and have a pastry cutter or be like me and cut it into 2 inch by 2 inch squares. take a bit of your mix and fill each piece of pastry and then pinch the sides up until you have a little triangle package of spinach and cheese yummyness.
Place each one on a cookie sheet lined with parchment. brush them with the beaten egg white and bake at 350 for 25 min or until puffed up and golden brown, When they come out the oven sprinkle the top with shreaded cheese of a bit of feta.
** You can also use a cupcake pan, push the dough up the sides and bottom of each cup then fill with the mix and bake. Then top with fresh diced tomato.
