Continuing the discussion from Soup recipe - Soylent swappable muggle food:
For those who are curious, there’s a large number of available hydroponics systems for home use that don’t require much upkeep - generally 1-3 hours a day. Basically come home from work and do your “gardening” and fish feeding.
Your major source of protein would be the fish (many systems recommend tilapia for optimal yields), though you would probably be best supplementing this with plant proteins, mostly shelling beans like soy or chickpea, which may be a bit more work, but dry very well. Using other beans would save time and energy in the harvesting, but add more sugars and starches, which you may be perfectly fine.
Lettuce and other leafy greens provide high yields and fast harvests, as well as high vitamin A, C and K content. Spinach is probably a good bet here, in terms of the tradeoff between overall flavor and nutrition.
From here, you need to add some other carb sources - tomato yields are good, and they preserve rather well with very high vitamin content. You have fiber and starches come from your beans.
I’m pretty sure grain beds are not feasible in an aquaponics/hydroponics environment, thought I’ve yet to see anything either way. It’s mostly irrelevant anyhow, since the harvesting would be very time and energy intensive for comparatively little yield.
Greens, beans, and fruiting vegetables are definitely the way to go.
I’ll see if I can cook up a recipe that will meet the minimum aquaponics yield for fish, since that would probably be your largest constraining factor.
Another thing to keep in mind - someone has to prep that fish. I’ve heard that many grocery stores are perfectly willing to gut and prepare fish you bring to them if you talk to them about it first.
