Do this with a regular onion, especially if you've already got one in the pantry trying to sprout. As it grows you'll get onion greens that work just like scallions in any recipe. Let it go to seed, now you have infinite onions, but depending on your local climate and luck, leave your original onion bulb to winter, and shoot again, and it has probably split into new bulbs, so you'll probably get 2 new onions from the plant, plus onion greens, plus seeds. Eat one bulb, and leave the other bulb to grow more onion greens.
I've never bothered using the seeds, I just keep a bulb or two in the pot. Been 5 years. I still buy onions if I want something like onion jam or French onion soup, where I need like 1kg of onions. But Ive never had to buy scallions, and I've got onion flavour all year long through onion greens (you can dehydrate them, and freeze them really easily too, to store them when you have more than you can use)
I also highly recommend throwing peas into a large tray of soil. Litteraly just grab a bunch of aluminium foil disposable oven pans if you need to, stab some holes in them with a knife, an inch or two of soil, some dried whole peas or fresh garden peas, a sprinkle of more soil or just a wet sheet of kitchen roll/paper towel on top.
You probably won't get peas, but you'll have tons of pea tendrils for salads. On my balcony it's the only "salad green" I've had any luck growing. I have a pretty black thumb. I can't even manage to sprout chia seeds without them moulding, and I've never been able to grow mint despite broad casting mint seeds directly into my garden, urging the gardening gods to spite me with weedy mint but no dice.
When I buy peas, 4/5ths go in the fridge to eat, the other 5th gets planted, and I'll get ~10 dishes from the tendrils vs 1 dish from the peas. Nutritionally the peas have more protein, but lentils are cheap, salad is expensive, so this works for my budget.
I think we just need tiny sinks in stalls, or rather, all public stalls should be designed as semi-ambulant stalls.
Growing up as a crutches user (hip deformity) I didn't fully comprehend that the standard stalls don't have sinks in them. I kind of knew they didn't all have sinks, but I didn't think too hard about it, I sort of assumed the reason most people flushed then came to the main public sink was to use the mirror or dryer.
I got to used to filling my personal bidet at the sink, using it, and washing it at the sink, all behind the privacy of a closed bathroom door.
When I had my hip surgery and no longer needed semi ambulant stalls, or disability access stalls, and it was just so inconvenient to fill and rinse a bidet bottle in a regular public bathroom I stopped using it.
Then a few months later started using the semi ambulant stalls again so I can use my bidet, because it turns out my lichen sclerosis doesn't like public toilet paper and I was getting really bad infections.
But yeah, personal bidet bottles are great, but they require a tap near the toilet.
Some public sinks are easy to fill a bidet bottle, but a lot aren't, you physically can't fit a bottle under the taps and because bidet bottles aren't common it can feel embarrassing to fill it at the public sinks. Disability stalls almost always have a proper tap and sink for washing toilet aid devices.
