Using the heel of your hand or a meat mallet, pound chicken breasts to even thickness, about ½ inch.Cut chicken vertically into evenly sized strips. (This step is optional, but makes it more like "chicken fingers" for kids)
Set up your breading station. Pull out three shallow, wide bowls (pasta bowls are perfect). In one, add AP flour, salt and pepper. In the second, beat the egg with the water. In the third, add the breadcrumbs and seasoning.
Using your dominant hand, dip a piece of chicken in the flour mix, turning to coat it. Place it in the egg mixture, being careful not to get the egg on your dominant hand. Using your non-dominant hand, cover the chicken in the egg mix, then place in the bread crumb mix. Use your dominant hand to coat the chicken in bread crumbs. Repeat with remaining chicken pieces.
Heat oil in sautée pan until shimmering. Add chicken in batches, making sure to give enough space for the chicken to not overlap. Cook until breading is golden, about 3-4 minutes, then flip. Cook until other side is golden.
Serve with your favorite sides. I prefer mine with a simple arugula salad dressed in lemon vinaigrette and topped with shaved parmesan. Enjoy!
