Spiced Pita Triangles

Preheat oven to 350 degrees, with rack in center. In a small saucepan, heat cumin and sesame oil over medium-low heat until fragrant, 5 to 6 minutes. Season with salt and pepper; add thyme, if desired.

Brush both sides of each pita round with spice mixture. Cut rounds in half, and cut each half into 6 triangles, each about 1 inch wide.

Place triangles in a single layer on a baking sheet, and bake until crisp and golden brown, 20 to 30 minutes. Transfer to a wire rack; let cool completely.
