I have a college kid here, and my husband knows to fend for himself so we are in different situations, however when I did/do cook for us I make one protein some veggies and something starchy for my son. I’ll nuke a potato, rice from Trader Joe’s or even just bread.
Rotisserie chicken is a savior, tons you can do with that. I make a lot of tacos, I use 96% lean ground beef. you can just set out bowls of stuff like a taco bar on the table and you can pick and choose what you like and they can have what they like. You said your family likes pasta, make pasta and nuke zoodles for yourself, then you can have those with whatever sauce you made. breakfast for dinner is a good one too. Make Canadian bacon or ham so you can have protein too. Eggo Waffles count as dinner in my house.
It’s very doable, ask your family for help and support, I’m sure some of them will pitch in. Especially if they’re afraid of what you’re cooking!
Enlist the kids in ideas and prep to make your life easier, you deserve it.
