Personally I almost always make stuff I can eat for more than 1/2 days. So it’s soups, stews, curries, etc. Everything pretty much boils down to protein + sauce + veggies anyway.
So it’s lentil soup/curry/chilli with a side of whatever you feel like. (Salad, bread, rice, quinoa, couscous, etc) Or chickpeas or some beans or whatever. Other times it’s just rice (think paella or risotto) or pasta.
