We love avocado toast. Nevertheless, we barely eat this treat due to its environemntal footprint. Avocados are grown overseas and require heaps of water! Sad life, but that unfortunately is the reason we minimize the consumption of this berry (yes it's a berry).
If we buy avocados, we either get them in a small oriental store around the corner where we know the avocados are coming from Spain (at least a small improvement compared to Mexico or South America) or on the farmer's market.
We also tried to grow our own little plant at home but unfortunately it started to rot after a few weeks - so no success here. If you were more successful in harvesting your own avocado, send us your secret!
