Back in the days when I was broke but had lots of time, I used to make up a big stew at the beginning of the week, using lentils in the way that meat eaters would use mince.
I used to leave them to soak overnight, and then fry up some onions and whatever other veggies I could find, then stick in the lentils with some tomato puree and maybe a tin of tomatoes, or a stock cube or made up bisto.
Day one, eat it with pasta or potatoes or other starchy thing.
Day two, eat it with another, but different, starchy thing, often pancakes made with wholemeal flour (yum).
Day three, stick mashed potato on the top and put it in a hot oven to make a shepherd's pie.
If necessary and available, I would add the odd vegetable to the mix as the days went on.
It was yummy, honestly.
I still use lentils in cooking now, but I tend to use the ones which come in tins, because I can. They weren't available in the 70s and early 80s. In fact, it was quite difficult to get decent lentils and beans at all, in the 70s. You had to go to hippy shops. Luckily, I lived near Oxford, where there was a fantastic hippy shop called Uhuru (or something similar - I am going to go and google it in a minute), and then Cambridge, which also had a fantastic hippy shop, this time called Arjuna, so I managed
ETA Considering I left Oxfordshire in 1979, I am pretty impressed that I managed to remember that name.
Uhuru it was, and it still exists
