Add pasta sauce, tomato sauce, and chicken broth to crockpot. Mix well.
Place in chicken breasts, and generously season the chicken breasts with salt and pepper. Coat the top with grated parmesan cheese. Cover and place on low for 6 - 6 1/2 hours.
Once done, mix the chicken sauce to coat evenly. Add mozzarella cheese, and top with oregano. Place lid back on pot until cheese is well melted (approximately 10-15 minutes). Serve over your favorite type of pasta.
