What are your go-to meals when feeding yourself is hard?

Currently having an "I'm depressed and in ADHD paralysis but need protein & something solid" breakfast - a Fairlife protein shake with buttered toast.

On good days, I try to have more nutritious breakfasts - eggs, fruit, etc. But this will do today. I was able to drag myself to the gym for a half-assed workout, thanks to my amazing trainer, so I need protein either way.

What are your go-to, easy meals (preferably high protein) when you're struggling to do much of anything?
