Spread Chile Dressing evenly over salad, sealing to edge of bowl. Cover salad tightly with plastic wrap. Chill for 4 to 24 hours. To serve, toss lightly to coat evenly. If desired, sprinkle with crushed tortilla chips. Makes 4 main-dish servings.
In a small bowl stir together mayonnaise or salad dressing, green chile peppers, chili powder, and garlic. Makes about 3/4 cup.
