No you’re right. Cook your veggies at the time you’re eating. Many can be cooked pretty quickly in the microwave if speed is the intent.

Do you have a freezer? Meal prep for 5 days, but freeze half into portions. Do two preps once to get some in the freezer, then just do it once a week from then on. If you do something different each time, after a few weeks you’ll be able to eat something different every night.

Pick things that freeze well. I find saucier things or minced things freeze best. Lasagne, stews, pulled pork, minced beef for burritos (if you’re adding rice, probably cook that on the day you eat it. I would avoid freezing rice I think.

Many Indian and westernised Indian dishes will freeze well, but I’d go for the vegetarian ones or test freezing smaller portions of dishes with hunks of meat. E.g. I find cooked chicken doesn’t freeze well, it dries out.
