Toast cardamom, caraway seeds, and peppercorns in a dry small heavy skillet over moderate heat, stirring, until fragrant and a shade darker, then cool. Grind spice mixture to a powder in grinder. Purée cilantro with spice mixture, garlic, chile, 2 tablespoons water, and 1 tablespoon oil in a blender until smooth (add remaining tablespoon water if necessary).

Cut pitas into 1/2-inch-wide strips and arrange in 1 layer on 2 baking sheets. Bake, switching position of sheets halfway through baking, until golden and crisp, about 10 minutes total. Transfer toasts to a rack to cool.3Serve dip with toasts and bell peppers.
