In a small bowl mix the paprika, garlic powder, onion powder, black pepper, cayenne pepper, dried oregano, 1/8 chipolte chili powder, smoked paprika and salt.
Thinly slice onion and cook in olive oil. Cook until caramelized about 30 minutes.
If you want a thinner chicken breast, flatten with mallet. I didn’t do this step. Season both sides of the chicken with the seasoning.
Heat a skillet and cook about 5-10 minutes each side. (if flattened takes about 5 minutes.) Cook all the way through.
Meanwhile mix the mayo, lime juice and remaining chipolte chili powder in small bowl.
Once chicken is done put a piece of gouda on and let melt.
To assemble spread the mayo, add the chicken with gouda on top. Top with tomato and carmelized onions.
