Preheat broiler. Rinse beans under cold running water. Make salsa: Place 1/4 cup black beans in the bowl of a food processor. Pulse until coarsely chopped; transfer to a bowl. Add remaining beans, tomato, scallions, jalapeno, cilantro, lime juice, and salt. Stir to combine; set aside.
Make chips: Cut each tortilla into eight wedges. Arrange on a baking tray; coat with cooking spray. Place under broiler, and bake until crisp and golden brown, 1 to 2 minutes per side. Transfer chips to a wire rack to cool. Serve salsa with chips.
