Yes, batch cooking!

One extra thing to consider is preparing something that can transform easily into many dishes.

We cook a "big meal" every weekend (now in winter time is chickpea+meat stew - "cocido madrileño"). It takes around 1 hour to make, but the time is not proportional to the quantity. So we make enough for 3-4 meals for my family of 3 on a big pot.

The nice thing about this stew in particular is that you can reserve the liquid, meat and chickpeas in separate containers in the fridge. The liquid is a very good base broth for soups (heat up, add some noodles, done in minutes).

The meat can be consumed cold, or can be the meaty base of other things (croquettes). We can also rebuild the dish by adding broth, chickpeas and meat into a plate and microwaving it (again, minutes). Or we can add some rice and have a "paella de cocido" (that takes a bit longer, around 25 minutes).

You have to adapt this idea to whatever is available to you in your area and your personal tastes. Perhaps you can prepare a big batch of mexican food, to eat in tacos/wraps/with salad. Or some curry base that can double up as a soup.
