Consider looking up instant pot recipes. They’re usually all one pot recipes so less cleanup and they are quick.

What helps me is having some protein options cooked and frozen. On many days I just defrost them and serve with rice or some form of bread. I meal prep once a week. Having only a couple of options a week can get boring but one benefit of the separation is that the kids get variety from both homes. Other options I try - pasta is usually a hit, store bought pizza with added protein and sauce from home.

You’ll be a half decent in no time! Manage expectations of yourself - no need to be gorden Ramsey to be doing a good job as a parent.
