In a deep plate, marinate the chicken with all the ingredients. Set aside for 30 minutes.
In the meantime, prepare the sandwich ingredients.
To grill the chicken: Preheat an indoor or outdoor grill to medium high heat. Place the chicken breasts on the hot grill and allow to cook for 10 minutes per side.
Once cooked through, cover with foil and allow it to cool down for 5 minutes before slicing.
When the chicken is ready, slice it into 1/4 inch thick slices.
Assemble the chicken sandwich: Spread 2 tablespoons of Sriracha Caesar Dressing at the bottom half of every sandwich.
Top that with a slice of cheese, some arugula, red onions, kimchi, chicken strips, sun dried tomatoes, and another slice of cheese.
Place the sandwich in a panini press and press on the grill for 4 minutes until the cheese melts and sticks all ingredients together.
Serve the chicken sandwich with fries and extra sauces for dipping.
Enjoy.
