When my kids were on swim team and time was crunched, I looked up a bunch of the disturbingly-named "dump meals" that could be assembled in advance, frozen, and then dumped into an instant pot for quick, hands-off dinners I could make while getting everything else done. That was really helpful! Search for "dump meal" or "dump dinner" plus your appliance/method of choice (crock pot, instant pot, baked, etc.)
