Corn, peas, carrots, broccolli, cauliflower, etc. Anything that most people boil.
I was raised with the notion that boiling a vegetable removes all the vitamins. I don't know whether that's true, but it led me to try another way to prepare my veggies. I'll never go back. Boiled veggies taste - ummm - yeah, boiled. Ick.
Melt 1/4 stick of butter in a pan, then add salt and pepper.
Stir infrequently on medium-high heat until the outside is lightly burnt, and the inside is done.
Raw carrots take longer than frozen corn, but both are delicious when finished. If you are in a hurry, you can cover the pan. That tends to make the finished product a little wetter, but it's all good.
