Toss steak fries with olive oil and coarsely chopped black pepper and rosemary(save a little of both pepper and rosemary for later). Spread on a baking sheet and bake at 425° until crisp,30 minutes.

Grate havarti on the large holes of a box grater. Divide the cheese into 8 3 inch rounds on a parchment lined baking sheet;season with pepper and rosemary. Top with the fries.

Bake until the cheese is browned around the edges,12 to 15 minutes. Remove with a thin spatula.
