I saw this on YouTube – Blind Frozen Pizza Taste Test – YouTube Video: https://www.youtube.com/watch?v=E9SeECaq30g (around 13:37 minutes long).
I spent several years where my diet was mostly frozen pizza. I would go to work, be there for 10 – 12 hours, come home to a quick supper of frozen pizza, then go to sleep. Frozen pizza could be cooked in almost no time. I used aluminum foil to save time on having to wash the pizza pan. I did take sandwiches with me for lunch sometimes.
