To begin, butterfly the chicken breast into two equal parts. Pound the chicken pieces with a mallet so that it tenderises and cooks evenly.
In a large bowl, marinate the chicken with ginger garlic paste, salt, red chilli powder,cumin powder, and lemon juice. Mix well and leave to marinate for at least half an hour.
Sprinkle some salt on the tomato, cucumber, and onion slices. Keep aside.
Heat oil for deep frying in a pan. In the meantime, generously coat the chicken fillets with breadcrumbs and dust off the excess. Deep fry the fillets until cooked and golden brown.
Spread the butter generously on both the sides of the bread slices.
To assemble, start with a layer of cucumber. Next add a layer of tomatoes. Sprinkle with some herbs of your choice.
Next, add the chicken fillet. Top with mustard sauce or any sauce of your choice. Finally, add a layer of onions before topping it with the other slice.
Grill the sandwich until the bread is toasted. Slice the sandwich into two.
The Grilled Fried Chicken Sandwich is ready to serve. Serve it with French fries and a dip of your choice.
