Me too! I’ve only just started to figure out how to make it work. The trick seems to be something like:

• Cook one bulk dish every couple days - rice Sun, carrots Wed, chicken Fri, broc Sat, etc
• Rotate in instant-use stuff like supermarket roast chicken, tofu, frozen veg + sliced meats, cherry tomatoes
• Play tetris using seasoning when reheating, like in 5-10 mins you could turn the above into a 1-pot rice stew with miso paste + instant dashi, or butter the rice+veg and serve western style, or add soy sauce for asian

I still suck at it though lol. Waste too much when things get busy + get pretty sick of chicken thighs :')
