I never seem to make lasagna the same way twice. The basics are the same, cheese, meat and sauce. It’s just the type of meat or sauce that is used and what cheese we have. We had left over Italian sausage from breakfast. My daughter had been asking me to make lasagna, so we made Italian sausage lasagna.
When you have left over ground beef or sausage, you can take left overs and turn into lasagna. Browning the meat is done when using left overs, so it saves time.
I prefer to use Italian blend cheese when making lasagna, but you can use mozzarella and a little mild cheddar too.
