FROZEN
Bring water to a boil, add frozen pierogi.  Simmer 5 minutes and remove.
 
Serving Suggestions:
Traditionally, pierogi are served with simple toppings: fried onions, melted butter, sour cream or pork rinds. These toppings may also be upgraded or replaced with more complicated sauces, as well as fresh herbs like parsley, chives, dill, mint, thyme, rosemary, tarragon or basil.
