There is no shame in supplementing with Huel, YFood or alike, even muti vitami is fine. I'm also a fan of a refreshing alcoholfree beer!
Lots of good advice here. I like frozen meals or even veggies to keep the routine on some of these days. They need to be heated in a pan opposed to frozen pizza which u just shove into the oven.
I can also recommend a simple rice cooker which u can set and forget, as it switches into warm holding mode when it's done w cooking the rice.
