Preheat oven to 250°F.

In a medium saucepan, over medium-low heat, combine butter, olive oil, garlic powder, oregano, and pepper. Heat until butter is melted.

Meanwhile, in a large bowl, combine parsley and oyster crackers. Pour melted butter mixture over crackers and parsley. Toss to combine until crackers are fully coated with butter.

Spread on a rimmed sheet pan, sprinkle with Romano cheese and toss gently to combine. Spread them out so they are in a single layer.

Bake for 15 minutes, stir gently (return back to a single layer) and bake for 10 more minutes or until golden brown.

Let cool completely before storing in an airtight container (but they taste best fresh!).
