You have to cook. I'm a good cook, but it takes an hour in the kitchen to prepare and average fast meal. (More or less, some meals are faster, some slower)
I do meal prep. I have a set of Pyrex food storage containers that I bought at Costco for $20 and change. I do an hour of cooking and it allows me to have breakfast, lunch, and dinner for three days at a time. It’s hard to imagine what life was like before this.
I like a variety of fresh meals. There is a difference in quality between vegetables you cut just before the meals and what you cut latter. Not everyone is that way, but I am. (this is also one reason I can't stand fast food - it is obviously not fresh.
