3 envelopes pizza dough mix
Your favorite sauce (my sauce of choice for this project is Hunt's 4       Cheese spaghetti sauce, comes in a can.)
Shredded Mozzarella
Grated parmesan
2 Italian sausages (I use sweet, but maybe you live on the edge)
Sliced pepperoni (I cut it into quarters)
Green peppers, cut up into about 1/2" pieces
Small can of mushrooms (fresh would be better)

  Squeeze the sausage out of the casings and fry it.  Make sure it's really well-cooked, as these don't take much time in the oven so it needs to be fully cooked when it goes in.  You don't want any raw sausage. Ick.
  Preheat the oven to whatever your pizza dough calls for.
  Mix all three of the dough mixes according to package directions.  Add some parmesan to the dough.  Just some, I don't know how much.  This is the way my mom taught me to cook.  (Wait until I post the recipe for Blueberry Slump..."put some blueberries in a pan with some water...")  But I digress.
  Anyway, three packages of Betty Crocker pizza dough will make 6 manageable-sized calzones that you can pick up and eat.  So divide the dough into 6.  Grease 2 cookie sheets, and spread the dough (grease your hands, too) into two shapes faintly resembling circles.  You can't move these once they're filled, so you have to do two and fill them, then do another in the middle. (If you really want to move them after they're filled, you could make them on parchment)  So you have your two circles, now spread the sauce and sprinkle the other fillings on the outside halves.  Don't scrimp on the mozzarella. Fold the other halves over so now you'll have a big enough space in the middle to make the third one.  The reason for doing it this way is that I only have two racks in my oven so if I want them all to be done at about the same time, I have to use two cookie sheets. 
  Sprinkle some parmesan on top and bake them.  Keep an eye on them, and you'll have to switch the top and bottom sheets so they'll cook evenly.  It only takes about 10-15 minutes at the most.

I don't often make stuff up from scratch, because history (MY history) has proven that no good can come from that.  But this one actually came out very well, family liked them!!  Of course it's not rocket science, it's pretty much a no-brainer as far as recipes go.  But those are the ones that work best for me!
There are almost unlimited possibilities here.  Anything you like on a pizza could go in, next I'm going to try fresh tomatoes and spinach, with some cheddar and a little feta.  Spring Street Market makes a 4-cheese pizza that is just the best thing I've ever tasted, and I believe they put cheddar and feta on it with the tomatoes and spinach.
