Ingredients
For the Sweet and Spicy Mayonnaise:
1/2 cup mayonnaise
2 Tbsp. Tabasco or other hot sauce
1/4 tsp. cayenne
1 Tbsp. honey
For the Chicken:
4 chicken breast cutlets, pounded to flatten
2 cups buttermilk (approximately)
1 tsp. salt
1 tsp. pepper
1/4 cup Tabasco
1-1/2 tsp. poultry seasoning
1 Tbsp. Cajun seasoning
1-1/2 cups Carbquick
1 tsp. garlic powder
1 tsp. minced onion flakes
1 tsp. smoked paprika
1/2 tsp. Italian seasoning
2 tsp. cayenne pepper
Avocado oil for frying
4 slices provolone cheese
4 Keto hamburger buns
Lettuce, Tomato, Pickles
4 strips bacon, cooked crisp
Instructions
In a bowl, mix all the ingredients for the sweet and spicy mayonnaise. Chill until ready for serving.

In a large bowl, season the chicken with poultry seasoning, Tabasco, a little Cajun seasoning, salt and pepper. Pour buttermilk over the chicken until it is covered. Marinate the chicken overnight.

After the chicken is marinated, prepare a plate with a mixture of Carbquick, cornstarch, garlic powder, minced onion flakes, smoked paprika, Italian seasoning, and cayenne. Dredge the chicken in the coating mixture and press it into the chicken. Lay the chicken cutlets on a baking sheet until all the chicken is coated.

Heat avocado oil until hot. Fry the chicken on both sides until golden. Keep an eye on it to make sure the coating does not burn. Carbquick fries dark quickly. This is why the chicken must be pounded thin, so that it also cooks quickly at the same rate. Drain the fried chicken on a wire rack.

To serve, place a slice of provolone on top of the chicken. Add lettuce, tomato and crispy bacon. Don’t forget the sweet and spicy mayo to finish. Delicious!!
