Place the cream cheese, lemon zest rosemary, garlic powder, and red pepper flakes in a bowl and mix thoroughly to combine. Transfer the cream cheese mixture to a piping bag or Ziploc bag with the corner snipped off and carefully stuff each of the olives with the filling. Set aside.
Set up a dredging station with three shallow bowls. Place the milk in the first bowl. In the second bowl, whisk together the flour, nutritional yeast, salt, and pepper. Place the breadcrumbs in the third bowl.
Double coat the olives by first dipping them into the milk, then into the flour, then back into the milk, then into the breadcrumbs – ensuring they’re fully coated during each step of the coating process. Place the coated olives on a parchment paper lined plate and pop them into the freezer so the filling can solidify a bit, about 20 to 30 minutes.
Place the oil into a large skillet over medium heat. Once the oil is hot enough – you’ll know when you sprinkle some breadcrumbs into the oil and it begins to sizzle immediately – fry the olives in batches until golden and crispy, 3 to 5 minutes. Transfer the olive to a paper-towel lined planed and continue to work in batches until they’re all fried.
Serve immediately with marinara sauce, fresh lemon wedges, and fresh parsley. ENJOY!
