Combine salt, chili powder and lime juice in a cup; mix well. Brush lightly over each tortilla. Cut each tortilla into 8 wedges. Spread tortilla wedges in a single layer on a baking sheet sprayed with nonstick cooking spray.
Toast in a preheated 400° oven for 7-9 minutes or until chips are lightly browned and crisp.
Remove from oven. Cool. Chips will firm up as they cool.
