This style of salad would fit in well with any type of vaguely Mexican meal. As is often the case with my material, it's more a set of directions/ideas than a set recipe. You can tweak the ingredients to your liking.
Whisk or blend thoroughly. If you make the dressing ahead of time you'll probably have to re-whisk this, especially if you didn't use the gelatin.
Combine ingredients in a large bowl, excluding tortilla chips or strips, pour dressing over and toss. Top with tortilla chips/strips, if using. They add a nice crunch.
