My MIL used to come home from work and get a dinner on the table for her husband and 5 kids ASAP. She always cooked the vegetables in a pressure cooker to expediency's sake.
I got one as a wedding gift in 1976. I don't recall doing anything fancy with it but if you needed to cook something fast and didn't care it it was overcooked, it was the way to go. I abandoned it after we got our first microwave oven.
I can still hear the sound it made when you cooled it rapidly under running cold water.
