Ever try to fool someone into thinking that some store-bought food was freshly prepared?

My parents don't have Fazolis at home, and I was able to get them to think that a whole Fazolis lasagna was one that I'd made from scratch (I didn't have time). Problem is now I have to learn to make lasagna for real, in case they ever call upon me to do it when I'm not at home. I guess that's a good thing, right?
