Half of one large green bell pepper, cut into ¼-inch slices
1 yellow bell pepper, cut into ¼-inch slices
1 red bell pepper, cut into ¼-inch slices
3 medium yellow onions, cut into ¼-inch slices
¼ head of green cabbage, cut into ¼-inch slices
2 tablespoons plus 1½ teaspoons fine sea salt
2 cups apple cider vinegar
1 cups light brown sugar
½ cup honey
1 tablespoon ground turmeric
1½ teaspoons dry mustard powder
1½ teaspoons whole cloves
One 1-inch cinnamon stick
1½ teaspoons whole allspice berries
¾ teaspoon celery seed
Directions
To a large bowl, add the tomato wedges, bell peppers, onions and cabbage and sprinkle with the sea salt. Stir until all the vegetables are equally coated in salt and cover with a kitchen towel. Let the bowl sit out at room temperature for 8 hours or overnight.
The next day, cover the vegetables with cold water, swish them around, then drain in a colander.
To a large pot, add the vinegar, brown sugar, honey, turmeric, dry mustard and drained vegetables. To a square of doubled cheesecloth, add the cloves, cinnamon stick, allspice berries and celery seed and tie the bundle with kitchen twine. Add the spice sachet to the pot and bring to a boil over high heat, then reduce the heat to medium-low and simmer until the vegetables have softened and the liquid has reduced by one quarter, 15 minutes.
Divide the vegetables into two 4-cup jars. Fasten the tops onto the jars and refrigerate for up to 3 weeks.
