I boil all my beans, quinoa, lentils and/ or rice for the week. If you want, you can freeze some beans and thaw them and use them when you need to.
Peel and clean some vegetables, not a lot of fancy stuff, just your favorite vegetables/ your staples.
And you have some basic stuff for the week to come.
I can make a chili in less than an hour with this things. Or burgers. Or whatever you need :)
And now, a recipe. Because this is a food blog :)
