This ignores the skill portion. I might ruin 3 meals before i make something edible that my body actually wants me to keep eating. I also keep coupons and know the local deals, my avergae fast food order ends up being about 30 minutes worth of wages. And tbh my work doesnt have a proper lunch break so I'm often still getting paid for 15-20 minutes i spend ordering and eating. It is still a loss compared to bringing food, which i usually do, but its not a massive loss.

Part of my problem as well is i dont work a defined shift and often end up spur of the moment working late. So if I pull something out to defrost or start soaking beans in the morning. Working ovetime can delay my cooking time from 5 pm to 8 pm, often cutting into the time i should be going to bed or getting other important shit done. I do meal prepping to help mitigate this but then im often eating the same lunch and dinner for 3-4 days straight, which can get difficult on the pallete.
