Whisk together the mayo, enchilada sauce, taco seasoning, green chilies, and lime juice in a bowl and set aside.
Preheat grill to medium high.
Lightly pound chicken to an even thickness. Season both sides generously with taco seasoning.
Grill chicken for about 4 minutes per side until it reaches 165 degrees.
Grill corn for about 8 to 10 minutes until lightly charred, turning frequently.
Remove both corn and chicken from the grill and allow to cool.
Strip kernels from corn cobs and place in a large bowl.
Dice chicken into small pieces (I did slightly larger than the onion and pepper) and add to bowl with the corn.
Add green pepper, onion and cilantro to the corn and chicken. Pour dressing over the chicken and veggies and fold together until combined.
Serve on a croissant.
