Sprouting.
It’s cheap, easy, nutritional and you can do it even if you have no access to other forms of local food. Isabella, my little girl, loves sprouting because she gets to grow sprouts herself and then eats them by the handful.
Start with lentils.
Take a cup or so. Put them in a bowl. Rinse them several times. Drain them but make sure they’re still moist.
Next day, rinse them a couple of times and drain them so their moist. Don’t let them ever dry out.
After about three days, they’re sprouted and you can eat them by the handful.
