Prepare the Chicken:

Cut each chicken breast into two pieces.
Place each piece of chicken breast between two sheets of plastic wrap.
Use a mallet or a rolling pin to pound the breasts until they are about ¼ inch (1/2cm) thick.
Season the chicken breasts with salt and pepper. Set aside.
Set Up Coating Station:

Set up three wide and shallow bowls/plates.
In the first bowl place flour.
In the second, beat eggs with mustard.
In the third bowl, mix breadcrumbs, salt, pepper, and paprika.
Coat the Chicken:

Start by coating the chicken in the flour mixture first, shaking off any excess.
Then dip in the egg mixture.
Finally, coat with breadcrumbs.
Fry the Schnitzels:

In a large skillet or pan, heat oil over medium-high heat.
Once the oil is hot enough, place a schnitzel into the skillet and fry until golden brown, about 3-4 minutes on each side.
Transfer to a plate lined with paper towels to drain excess oil.
Serve:

Serve with fresh salad and lemon wedges.
Enjoy! Squeeze some lemon on top of the schnitzel if desired.
