Notes
Tips and Tricks
Let the chicken cool slightly - Warm chicken is fine, but very hot chicken can soften the lettuce too much.Chop everything small - Smaller pieces make the salad easier to scoop with tortilla chips.Drain the beans and corn well - Extra liquid can make the dressing thin and watery.Use seeded tomatoes - Removing the seeds helps keep the salad from getting soggy.Add the chips at serving time - Keep the tortilla chips on the side until ready to serve so they stay crisp.Adjust the heat - Use hot salsa or chopped jalapeños if you want more spice.
Storing
Store the salad - Place leftovers in an airtight container in the refrigerator for up to 2 days.Store the chips separately - Keep tortilla chips in a sealed bag or container at room temperature so they stay crisp.Store the dressing separately if making ahead - Keep the dressing in a small airtight container in the refrigerator. Add it right before serving.
