Place the dinner rolls in a lightly greased baking dish, keeping them connected if using pull-apart rolls.
In a small bowl, whisk together the melted butter, olive oil, The Holly Tree Organic Oregano Leaves, Organic Basil Leaves, Organic Black Pepper Powder, Organic White Pepper Powder, and Organic Chili Flakes.
Brush the herb butter generously over the tops and between the cuts of the rolls so the seasoning seeps into every layer.
Sprinkle the grated Parmesan evenly over the rolls, followed by the chopped parsley and sesame seeds, if using.
Cover loosely with foil and bake for 10 minutes.
Remove the foil and continue baking for another 8–10 minutes, until the tops are golden brown and the Parmesan is lightly crisp.
Brush with a little more herb butter immediately after removing from the oven and finish with an extra sprinkle of The Holly Tree Organic Oregano Leaves.
