There is a strainer that collapses on itself when not in use, but when open, it can fit most sauce pans. They're lie 4 bucks and my last one lasted 10plus yrs. That said, steaming isn't where the flavor is. Chop basically any veg into 1/2" chuncks, toss with a little olive oil and sea salt, then put on a foil lined cookie tray and bake at 350 deg for 30-45 min. It is fantastic with basically anything.
