Place the pecans a food processor and pulse until finely chopped (go easy — you don’t want a paste). Add the cereal, spices, and honey and pulse a few more times to combine.
Set up two large shallow dishes in an assembly line. Beat the egg in the first dish and place the pecan/cereal mixture in the second dish. Line a baking sheet with parchment paper to hold the breaded fillets, and place at the end of the assembly line.
Season the chicken pieces with a little salt and pepper. Working with one piece at a time: dip in the egg to coat evenly; and then dredge in the pecan/cereal mixture, pressing down to make the coating adhere. Try to use one hand for the dry breading and one hand for the wet– otherwise, your hands will end up a mess. Place the breaded chicken on the prepared baking sheet and repeat with remaining pieces.
Place baking sheet in the oven and bake chicken for 20 minutes or until cooked through.
