Add 1 teaspoon of marinara sauce, a pinch (about 2 teaspoons) of mozzarella cheese, and 1-2 teaspoons of pizza toppings of your choice. Repeat until all wonton wrappers are topped.
Very lightly brush the edges of each wonton wrapper with water. Fold 2 opposite corners of the wrapper into the center, then fold the remaining 2 corners over the top of the first 2.
