by vanillasugarblog.com

2-3 sweet potatoes, chopped into 1-inch cubes
extra virgin olive oil
butter
salt and pepper
caramelized onions
few dashes of worcestershire sauce
couple dashes of Tabasco sauce, optional but wonderful

Caramelize some onions (about 1 giant sweet yellow onion) after it's done caramelizing add a few drops of the Worcestershire sauce, set aside. 
Heat up skillet with some EVOO and fry up the sweet potatoes until nice & crispy, season with salt and pepper. 
Towards the end of cooking add a few tablespoons of butter to the skillet to melt into the hash. 
Then add in a few dashes of Worcestershire sauce, mix until combined.
