Chicken Parmesan

4 boneless/skinless chicken breast halves
1 egg, slightly beaten
1/2 c. seasoned bread crumbs
2 T butter
1 3/4 c. spaghetti sauce
1/2 c. mozzarella
1 T grated parmesan
1/4 c. chopped fresh parsley
flour

Using the palm of hand or a meat pounder, flatten the chicken to an even thickness. Roll chicken in flour on both sides and then dip the chicken into the egg, and then the crumbs to coat it. In a skillet over medium heat, let the butter melt. When melted and hot, brown the chicken on both sides. Add the spaghetti sauce. Reduce heat. Cover. Simmer for 10 minutes. Sprinkle with cheeses and parsley. Cover, simmer 5 more minutes, or until the cheese melts. Can serve over pasta. Serves 4.
