For Cajun Seasoning

- Paprika
- Ground black pepper
- Italian seasoning – If you do not have Italian seasoning then add 1 tbsp dried oregano and 1/2 tbsp dried thyme.
- Salt
- Cayenne pepper – You can substitute it with any spicy red chili powder. Skip if you do not prefer spicy dishes.
- Onion powder
- Garlic powder
For Cajun Chicken Marinade
- Chicken – I have used boneless skinless chicken breast. You can also use boneless skinless chicken thighs.
- Olive oil – Or use vegetable oil.
- Lime Juice – Substitute it with vinegar.
For Cajun Sandwich

- Sandwich bread/ hamburger buns – You can use any sandwich bun.
- Onion – I have used red onion for assembling this chicken sandwich. Substitute it with white onion or skip it if you do not have them.
- Mayonnaise – I have used veg mayonnaise. Substitute it with egg mayo, garlic mayo, or any other flavored mayo.

- Fresh Tomato

Cooking tips
- Pound the chicken breast or slice it into half. This helps the chicken breast to cook evenly.
- Marinate the chicken for 2 hours or overnight in the refrigerator. It tenderizes the chicken and the seasoning enhances the flavor of the chicken. It will also keep the chicken moist while you grill it. However, if short of time, you can marinate for 30 minutes.
- Grill the chicken – Heat the grill pan on medium-high heat. When the pan is hot enough, place the chicken in it. The heat will seal the outer surface of the chicken and lock the juices of the chicken inside. That makes the chicken crispy outside, and soft and juicy inside.
- Cook the chicken – Make sure to cook the chicken until it is cooked through. You can make a small cut in the middle to check that it is no longer pink in the middle. It should be white or opaque in the middle. Or cook until the internal temperature reaches 165˚F.
- Cook the chicken until char marks appear on it. It will give a nice smoky flavor to the chicken.
- Give at least 10 minutes of resting time to the chicken, once it is cooked.
- To adjust the spiciness of Cajun seasoning, reduce the quantity of cayenne pepper in the seasoning.
