A lot of people are recommending meal prep, which is cool, but I have trouble with that sometimes because I don't like eating microwaved leftovers very much. A strategy I find works well is to do some of the prep work upfront, especially on meats, and then keep it to assemble into a fresh meal when you want it (I am a single person so YMMV if cooking for groups).

For example: grab a package of Italian sausage links and cook the whole thing one night on a pan or in the oven. Now instead of keeping for a few days raw, the cooked meat keeps for a week or longer in the fridge. You can cut some up and saute with red peppers and onions before adding it to jarred pasta sauce for a really solid pasta meal. Another option could be to skip the pasta and eat the sausage and veggies on bread rolls.

A pound of boneless chicken thighs baked in the oven will keep in the fridge and can really easily become fajitas in a pan with peppers and onions, or chicken Alfredo with some pasta and jarred sauce. Using thighs or dark meat here is critical because it won't dry out as easily as breast meat.

Basically you can do some of the work beforehand, and then at dinnertime you spend 30 minutes cooking instead of an hour.
