What kind of ingredient this is

lentils sits in the pulse / legume family. Pulses are the cheap protein-bulk ingredients (peas, lentils, chickpeas, fava beans) that grain-free formulations leaned on after the 2007 to 2018 reformulation wave. Sniff penalizes stacking when three or more pulse-family ingredients appear in the top 15.
