Separate a can of refrigerated breadstick dough into sticks. Flatten the breadsticks and cut each lengthwise into 2 or 3 thin strips. To make the brooms, snip the bottom inch with scissors and twist the rest to form a handle. To make the wands, dip the dough tips in beaten egg and paprika, then twist. Place the broomsticks and wands on a parchment-lined baking sheet, brush with egg and sprinkle with grated parmesan. Bake at 375 degrees F until golden, 8 to 10 minutes.
