I've found meal prepping to be a fantastic solution. I can make 5 meals in about an hour with my 4 burner stove. These meals are cheap, help me eat a lot of vegetables, and allow me to easily hit my macronutrient goals for strength training.
Not to mention, I assume the one hour doesn't include time to clean up, which for me is one of the biggest drawbacks of cooking.
I only mention this because I only realized this after I purchased the dishwasher. And so I spend time researching and "optimizing" in hopes of finding the next dishwasher in my life, which is how one falls into the trap this article describes.
