I've found that cooking extra food with the intent of freezing it in individual portions is a game changer for when I'm alone at home - my fiancée can also pack them for lunch. Rice, curries, ragoûts are really nice to get out of the freezer, put on a plate in the microwave and eat a few minutes later.
Look at Souper Cubes (or any silicon knockoff) for the molds.
Batch cooking is the only way to have two working adults. I love to cook though, so at home, one cooks the batch part and the other does a different meal for the weekend.
We think our cooking is much better than almost all restaurants we go (and we heard from others that our guests usually thinks the same).
Living with a shared kitchen I had a neighbor (+gf) once who hated cooking. His solution was to cook only once per month. It was quite hilarious, he made about 40-60 meals in one day. Giant pots everywhere.
He would print a menu card for the month with all the 3-4 course meals. He would set the table, light candles, poor the wine and argued what to microwave.
