Bob,
Do you know how to harvest said seeds? I have a San Marzano producing right now in my yard!
Not much fruit left though.
One of our plans for the oven is to have a weekend where we:
1) make sauce from our own tomatoes..
2) make our own mozzarella (only takes about 30 minutes!)
3) make pizza dough using the leftover whey from the mozzarella (makes an amazing pizza dough)
4) make some pizza using just those ingredients and some herbs from our garden (oregano, sage, etc) and perhaps some homemade chevre or something of the sort...
The only thing more totally back to nature would be if we were dairying our own milk, but darn, we love this stuff!
