Poor Soil & Recovery - good for Radish, Marigold and Tagetes. And maybe Cornflowers.

[RobinHood]

What about radish as food? this are a spacial food too, not for you, but for the soil, radish doesn't need lot /K/N/P/ consumption, but radish also very low carb - it shouldn't kill the hunger a lot (less or max 60 satiety-points), the soil will restore with radish. Tagetes and marigold for soil restauration also good.
And if Marigold and Tagetes in nearby other fruits, they will profit a bit more (faster growing).

And cornflowers, will have nice color contrast for tagetes & marigold. cornflower => just decoration.
