Cut the chicken into smaller pieces. Make sure they are not too thick. Put the chicken in a large bowl.
2 fillets Chicken breasts
In a small bowl, mix the flour and the spices. Add the mix to the chicken and mix it by hand until the chicken is coated as even as possible.
1 tbsp All-purpose flour, Black pepper, Salt, Paprika
Beat the egg with a little mustard. Add the mix to the chicken and mix by hand until coated.
1 Egg, Mustard
If you are using bread crumbs, put them on a large plate
2 tbsp Bread crumbs
Warm a little oil in a frying pan. When the pan is hot, lower the heat to medium.
If you are using bread crumbs, coat each piece of chicken in the crumbs.
Put the pieces in the pan. They can be close together but don't overcrowd the pan. Be careful, the oil might splash.
Cook the piece until the top turn white and the bottom is golden brown. If the cuts are thick, you may need to lower the heat and fry them a little longer so the middle would be ready.
Flip the pieces and fry until the bottom is golden.
When ready, put the pieces on a serving plate line with paper towel, and continue with the rest of the chicken.
