Fry pancetta in sauté pan until crispy and remove from pan, leaving the pancetta grease.
At medium heat, add diced shallots and sauté for 2 minutes before adding garlic. Stir garlic in for 1 minute and season with a generous amount of salt and fresh cracked pepper.
Add in halved brussel sprouts and stir to combine. Cover and cook for 10 minutes or until brussels are cooked through, stirring often. Add more salt and pepper to taste.
Remove lid and sauté to add browning to the brussel sprouts for about 5 minutes. Add pancetta and truffle oil into the pan.
Cook for 2 more minutes, remove from heat and enjoy!
