Do I know what I'm doing? Not really. But that's how I live my life in general.
The biggest obstacle is my wife, a really good cook who still believes meat is critical for health. But living in an Islamic country has reigned in her Slavic enthusiasm for pork, and my kids kick up a shitstorm whenever she cooks beef (don't ask, I can't explain it). On the upside, she cooks a lot of dishes with beans and always makes salad.
This morning, when I opened the fridge, a place I rarely explore unless there's beer in it. It seemed all our breakfast food had a connection to animal products. Milk. Eggs. Butter. But I found bread, peanut butter, honey, and tomatoes. Good enough to start with.
The highlight was the tomato. I had better plan ahead for tomorrow.
