Use https://fallingfruit.org/ to get free, fresh food. Maybe once a week ill hit up the fruit trees and get a huge amount of free citrus, mangoes, almonds, loquats and fresh herbs (lemongrass, rosemary and lavendar mostly). There is also a ridiculous amount of olive trees on public land in my city, if I had the time and inclination to brine them properly I could probably make 20kg a week during the fruiting season. But I could never use or even give away that much olive.

I havent paid for limes, lemons, oranges or mandarins in years and I consume at least a couple kilos a week.
