Ive been growing my own microgreens lately. Mostly Arugula, asian greens, cilantro, different mixes but primarily brassicas and such.
They are ridiculously good on almost anything and easy to grow. Also they have up to 40x more nutrients than adult versions of the plants. I just drop them on everything from eggs to burgers to tacos to pizza to salads to
I grow them indoors without soil and get about 4lbs from 2oz of greens every 10-20 days depending on what I feel like growing. Its just a 1x2 tray, no soil used, and doesn't need much sun. You can get about 30-40 trays per lb of seed.

Basically, fresh grown, super nutritious, low effort, cheap food. If you want to try something different, or want to grow your own stuff... give them a shot. I can help point anyone in the right direction if they want to try it.
Good stuff
