To be honest, I think the best way to get Lemmy to grow in the near term will probably be getting more people to use both Mastodon and Lemmy, rather then hoping more people will shake away from reddit. I’m active on Lemmy but probably use mastodon more.
The premade soylents are pretty good, and I regularly have them with a protein bar as my lunch. They’re pretty expensive in my opinion, so I try and look for them on sale, but the ease of not having to prep lunch is often worth it. I try and keep it under $2 a bottle for the 14oz ones, which still feels expensive to me, but some of the lunches I prep are around that cost, and it’s way cheaper than going out to eat (I keep a spare one at work in case I ever forget to bring lunch)
