Make the Dressing: Put your Greek yogurt, mayonnaise, and lime juice into a blender. Add the chipotle peppers, adobo sauce, salt, garlic, and chili powder. Blend it until it is perfectly smooth. It will turn a beautiful light orange color.
Mix the Salad: Grab a large mixing bowl. Toss in your shredded chicken, black beans, corn, and diced peppers. Add the red onion, romaine lettuce, and fresh cilantro.
Combine: Pour that creamy dressing right over the chicken and veggies. Use a large spoon to stir everything together. Make sure every single bite is coated in that amazing sauce.
Taste and Adjust: Give it a quick taste. You can add a little more black pepper or salt if you think it needs it.
Serve: You can eat this right away, or you can put it in the fridge to chill. It actually tastes even better after a few hours because the flavors dance together!
