In a deep, clear glass bowl, start by placing the lettuce. For each layer, begin by placing it around the perimeter of the bowl to define each layer and then fill the middle with the rest.
The second layer is the black beans and the third is the corn.
After the corn, add a layer of tomatoes and top it with a layer of cheddar cheese.
Finally, sprinkle on the olives, scallions and crumbled tortilla chips if you're craving some crunch.
Mix the ranch dressing and taco seasoning until fully combined.
Serve on the side of or drizzle over the salad.
