I didn’t weigh or count these, so we’ll just say for recipe purposes “about yea many”.Along with the green tomatoes, I added two big sweet onions, and four bell peppers, two green and two red.  Coarse chop all of that then spin it in a food processor to get the final mince on.  Stir in two tablespoons of kosher salt and let drain in a colander for a while, then add to a big pot.  I added yellow and black mustard seed, whole coriander seeds, a dollop of Dijon mustard, black pepper, many cloves of garlic, minced, some ground cumin, granulated garlic, granulated onion, 1 cup of sweetener, and one cup of vinegar.
Bring to a simmer and let it bubble for 20 minutes or so.  I managed to cram everything into 5 wide mouth pint jars.  Process in a water bath for 20-30 minutes.
