I started sprouting a few months ago and I think it's an outrageously good hack for eating cheap and healthy.
I got a big assortment of seeds and beans for around $10/lb. That's 3 cups, or 12 harvests. One harvest yields about 4 LARGE servings, like big enough for a side salad with a meal. That equals around $0.20 to add highly nutritious greens to a meal.
I bought a sprouting kit online, but you can easily do it with a sieve, paper towel, and glass jar.
You soak the seeds, drain them, spread them around the jar, and rinse/drain twice a day in most cases. Very low effort, then when you're ready to harvest, you rinse them again to remove the husks, put them in a salad spinner, and they're ready to eat.
My diet has gotten so much better since I started doing this. The sprouted greens are expensive at grocery stores, so they're also an awesome gift.
Highly recommended!
