1Preheat your oven to 350°F (175°C) to keep the chicken warm if needed.
Slice the brioche buns in half and lightly toast them in a toaster or on a skillet until golden brown.
Spread a generous amount of spicy mayo on the bottom half of each toasted brioche bun.
Place one piece of spicy fried chicken breast on top of the spicy mayo on each bun.
Add a layer of lettuce on top of the chicken for a fresh crunch.
Spread more spicy mayo on the top half of the brioche bun, if desired.
Place the top half of the bun over the lettuce and chicken to complete the sandwich.
Serve immediately and enjoy your delicious Spicy Chicken Sandwich!
