Thanksgiving week and we grew up eating very fresh veggies usually covered with olive oil. I never tried green bean casserole until I was in college and went to a friend's house for the holidays. Here's a version of my Mom's recipe. Also, purple green beans will change color when you cook them to a dark green! When we went to the Farmer's Market and bought the purple beans, I was so excited! After cooking them, they were yellow, green, and dark green. It seemed like a trick! But they still tasted delicious!
