home made spice mix?

basically, in the past, i've bought dry meals that are basically red lentils + dry spices, and they make a nice acceprible meal from just boiling, high in protein and cheap

i wanted to make my own spice mix to save money, something i can make a whole jar of, and put a tablespoon or w/e with a bunch of red lentils, boil, and have a nice meal

- this also comes from the fact that i will be studying full time in a year or two, and i'm trying to explore new cheap, but nutrtitious meal options that i can either just microwave, or nuke a large amount of, and have several days worth of meals ready

any suggestions?
