Heat a large skillet to medium heat and add olive oil. Add jalapeno peppers and cook about 5 minutes, flipping them through, until softened and starting to char. Remove from heat and set aside.

To the pan, add spinach and garlic. Toss and cook a couple minutes, until spinach is cooked through. Remove from heat and set aside.

Pound the chicken flat with a tenderizer or rolling pin to about a half inch thick.

Season the chicken with Cajun seasonings, salt and pepper and add to the skillet. Sear about 2 minutes each side, then reduce heat to low and cook until chicken is done throughout. Use a bit of cooking spray to avoid sticking if needed.

Top chicken with spinach, tomato slices and jalapeno pepper slices, then top with a half slice of cheese.

Cover the pan until cheese is melted. Serve!
