Radishes Can Likely Grow in Lunar Regolith - Universe Today:
“We’re trying to show astronauts can use horticulture to grow their own food on the Moon,” said NASA scientist Max Coleman. “We want to do one tiny step in that direction, to show that lunar soil contains stuff which can be extracted from it as nutrients for plants.”
They were about to start doing hands-on tests of soil sensors that might eventually be used on the Moon when the stay-at-home orders were issued. While the team wasn’t able to bring home any lunar simulant or the soil sensors, Coleman decided to innovate. He placed an order online for some desert sand, which doesn’t have any organic matter, so is a good stand-in for the lunar regolith simulant.
[...] He decided to use radish seeds, and ordered them online for home delivery, too.
[...] Also, radishes don’t require a lot of water to germinate, so they provide a good test of what could grow quickly in one lunar day, (28 days, with 14 straight days of sunlight.)
[...] The results were quite surprising: Radishes in the section with the least water germinated first and best, which was interesting because, Coleman said, “we want to see how little water we can get away with.”
The team’s research is helping them develop a small scientific payload on a commercial spacecraft going to the Moon, which, if selected, would be delivered to the lunar surface through the NASA Commercial Lunar Payload Services (CLPS) initiative. The team planned to develop the experiment as a suitable payload for a CLPS spacecraft in terms of size, mass, power requirement, and communication needs.

That deserves at least a moment of semi-serious thought.
When you leave home, even here on earth, you leave behind some comforts, and you have to adapt to a new reality.
So, we send some settlers to a new world. They're going to have to adapt to new realities. If you carelessly leave a door open, you don't just run up the heating/AC bill - you've dumped all your breathable atmosphere. Likewise, you're going to have to get used to the food available. If radishes are what's available, then radishes are what you'll eat.
A lot of serious thought will have to go into what is carried out there to be cultivated. And, a lot of serious time and effort will go into that cultivation. I really doubt that there's going to be anything comparable to Wonder bread available, for a long time.
