Cut each chicken breast horizontally, stopping 1/2 inch from edge. Open each breast and pound to 1/4 inch thickness or so the chicken is the same size of the Naan bread(see note below). Sprinkle with salt and 1/4 teaspoon of the pepper.
In large pie plate, place panko. Stir in cumin, cayenne, garam masala and remaining 3/4 teaspoon pepper.
In another pie plate, place 1/2 cup of the flour. In third plate, whisk egg and mayonnaise with paprika; whisk in remaining 3/4 cup flour until smooth.
Dredge 1 chicken breast in flour; shake off excess. Then dip chicken in egg mixture to coat; next dip in panko. Repeat with remaining chicken breast.
In large non-stick skillet over medium heat, place 2 tablespoons olive oil and 1 tablespoon butter. Add chicken and cook, turning once, about 2 minutes per side or until internal temperature reaches 165°F Remove and keep warm.
Wipe skillet and add remaining 1 tablespoon oil and 1 tablespoon butter. Add garlic and stir until fragrant. Briefly heat Naan in garlic oil, turning once, until soft and golden. Place 1 chicken breast on each Naan and top with tomato slices, lettuce leaves, a generous tablespoon each of Sweet Date Sauce and Tangy Yogurt Sauce and remaining Naan. Cut each sandwich in half and then, half again. Serve with extra sauces for dipping. Two Naan-wiches make 4 servings. Enjoy!
