My Yummy Italian Chicken (not sure of real name)

1/4 cup olive oil, divided
1 cup onion
2 garlic cloves
28 oz crushed or diced tomatoes
2 tsp sugar
1/2 tsp salt
1/4 tsp pepper
4 boneless skinless chicken breasts
1/3 cup bread crumbs
1/3 cup parmesean cheese
1 egg, beaten
1/2 cup mozzerella cheese (Logan likes it best when I use string cheese)

Heat 2 tbs. oil--cook onion & garlic for 2 minutes. Stir in tomatoes, sugar, salt, and pepper. Heat to boiling. Reduce heat and cover.

Flatten chicken to 1/4 inch. Mix bread crumbs & cheese. Dip chicken breasts in egg, then bread crumb mixture.

Heat remaining oil over medium heat. Cook chicken in oil 10-15 minutes, turning once. Pour sauce around chicken. Put mozzerella cheese on top of chicken. Cover & heat till melted.
