A couple of years ago, while standing on line in a grocery store, I saw the man in front of me place a huge sack of dried mung beans on the belt. The thick, white bean sprouts seen on salads in restaurants, salad bars, and so on are grown from mung beans.

I had never before seen so many mung beans in one place. You can make a big jarful with 2 tablespoons. “What are you going to do with all those mung beans?” I asked. He said he had seven kids. Oh.

The cost of nutritious food is an ongoing concern, and here is a great solution. You can cook little green mung beans like any other bean, in a pot of hot water or in a crockpot all day long with vegetables. You can mash them up a bit and pour them over grains, including brown rice, or roasted vegetables, like spaghetti squash. Or you can sprout them.

There are a few significant misconceptions about sprouting, and I’m about to dispel them. First, you don’t need a special expensive jar with a special, equally expensive lid. A few days ago I poured a couple of tablespoons of dry mung beans into a clear, medium-large glass jar. A recycled spaghetti sauce jar is perfect. You just want the jar to be clear so you can see the sprouting progress. Kids love this, by the way.

I filled the jar with water, and left it to sit on the kitchen counter all day (or all night if you prefer).

At the end of the day (or the next morning), I drained out the water through my fingers, filled it with fresh water and emptied it out again a few times. Then I turned the jar on its side with the damp, swollen beans spread out along the bottom of the jar. I returned it to its spot on the kitchen counter. The primary consideration is to place it where it won’t roll off the counter. You could use a kitchen towel for this, but there are plenty of other options.

Also, you don’t need to sprout beans in the dark. They don’t know if it’s dark or not. The plant won’t care about light until it sprouts its first leaves, which will not happen before it sprouts. Over the years, before I had this realization, I found many jars of moldy sprouts in the cabinet days to weeks after I had carefully placed them there. No more. I never forget now, because the jars are right in front of me, on the kitchen counter.

Next step: Twice a day, morning and evening, I rinse the beans, drain them through my fingers, and replace them on the counter. If you forget one time, or even two, don’t worry. Just fill the beans with water again for a few hours to rehydrate them, and then keep going.

Within 2 days, I see tiny white tails beginning to emerge from some of the beans. You can eat them raw now if you’d like, while they are still mostly bean. Within 3 days, the tails are really growing, and in 4 days, they are a couple of inches long. Now they are mostly sprout, and the jar is filling quickly. You can eat them at any of these stages.

I like to sprinkle bean sprouts on salads of course, but I also like to consider the sprouts the main part of the salad and add a few other simple salad veggies, like tomatoes or cucumbers. A sprinkle of salt and a splash of olive oil, and you’re good to go.

By the way, you can make the salad right inside the glass jar you used to sprout your mung beans, wrap it up, and take it to work for lunch. The sprouts won’t wilt like lettuce does. Cheap, delicious, nutritious, and filling. What more can you ask?
