Due to my recent change to a vegan diet I had to come up with some substitute for a cheese that would be added to traditional polish pierogies. Thanks to science I am able to use Nutritional Yeast instead, which not only adds an amazing cheese flavor but also boosts your system with Vitamin B12!
Step 1: The Filling
Peel 4 Lg potatoes
Boil them until soft (like for puree)
Chop a few cloves of garlic and 2 onions
Saute with some olive oil on medium heat
