You have lentils we have brown beans. The saying is: honger maakt rauwe bonen zoet.
Hunger makes raw beans taste sweet. No need to cook just wait till the family is starving and ready to break teeth on it. I think it's just for picky or spoiled eaters or those always complaining. If hungry you eat everything is the motto.
