How can I plan flexible meals around an unpredictable freelance schedule?

[Paisley_T]

I'm a freelance graphic designer working from home, and my erratic schedule makes consistent meal planning a constant struggle, leading to too much takeout. I want to develop a flexible system that accounts for my variable workload and energy levels, not just a rigid weekly calendar. For others with unpredictable jobs, what practical meal planning strategies have you found that accommodate last-minute changes? How do you balance batch cooking with the desire for variety, and what are your go-to quick recipes for those days when you have zero motivation to cook? I'm also interested in how you manage grocery shopping and reduce food waste when your plans shift unexpectedly.
