Ordering a known meal from a known restaurant is definitely easier than home prep. Ordering a "probably fine" meal from a "probably fine" restaurant requires extra cognitive load over cooking at home. (Some days I struggle with simply selecting a new meal from a restaurant. On those same days, I can happily spend an hour cooking a new-to-me recipe without any problems.)
For me, there were two keys:
1. I love cooking and find it to be a nice meditative experience, but back then I was working 16-18 hour days and I simply didn't have the energy to deal with all of the other stuff you gotta do before and after you cook. This was a good middle ground.
2. I could adjust the ingredients to my liking - don't put in the cilantro, for example, or add some extra chili to make the sauce spicier.
