Chicken Parmesan

This is one of my favorite foods and a go to recipe. First of all, I don't even need to use a recipe anymore. Second, I usually have all the ingredients on hand. During the winter I'll make pasta to go with it, but my favorite this to use is spaghetti squash. It's delicious.

4 boneless, skinless chicken breast halves
1/3 cup Italian-style dry bread crumbs
1/3 cup grated Parmesan cheese
1 egg beaten
2 tbsp olive or vegetable oil
2 cups spaghetti sauce
1/2 cup shredded Mozzarella cheese

Flatten chicken to 1/4 inch thickness. Mix bread crumbs and Parmesan cheese. Dip chicken into egg; coat with bread crumb mixture.
Heat oil in 12 inch skillet over medium high heat. Cook chicken in oil 10 to 15 minutes, turn once, until juice is no longer pink when centers of thickest piece are cut. Add spaghetti sauce. Reduce heat to low. Cook 2-3 minutes or until sauce is hot. Sprinkle mozzarella cheese over chicken.
