Grilled-Vegetable Flatbreads

Contributed by Grace Parisi

Light a grill. Cut the grilled vegetables into bite-size pieces and scatter over the pitas. Carefully transfer the flatbreads to the grill and cook over moderate heat just until warmed through, about 5 minutes. Transfer the flatbreads to a platter and drizzle the walnut dressing over the vegetables. Scatter the pecorino over the flatbreads and serve.
