Can using paper plates and plastic utensils fully replace using regular dishes?

Not completely. I use about 90% paper plates but not the utensils. Steaks and such need a more substantial plate. Then there are bowls. Regular bowls for me.

My sister does that

Not really

It almost does in my apartment. Except some of my utensils are regular 🤷🏾

No, they’re lousy for the environment, so don’t use them
