I was going through this phase. So, i just don't cook at lunch or breakfast. Eat whatever you want, I don't care. Eat some cereal if you can' figure it out. Make your own omelets. Here are some deli meat and greens.
That's how I felt like. Eat some ramen noodles if you want.
You just need a break. After a week or two I need to become creative again. That's how I am. Make use of a crockpot, dump everything in there. Make a chili. Eat the chili with cornbread/bread one day and another day on pasta. Any chili leftover will be combine with a can of beans and make tortilla/quesadilla/burrito versions.
Order for take out when you have feel stressed. But, after a few days, I realize that what we ordered is not enough variety, so i go back to my own creative cooking.
Or cook enough pasta for 2 days. One day, open up a jar of red sauce and mix it with ground meat. Another day, open up a jar of pesto and mix it with the remaining pasta. That's it.
And don't clean up afterwards. Leave that to whoever that didn't cook.
