Step 1

To a large mixing bowl, add the vinegar, ketchup, brown sugar, salt, and whisk to combine.

Step 2

Add all remaining ingredients and toss to coat evenly. Toss well to make sure everything has been well-coated.

Step 3

Transfer salad into a large Tupperware-type container with a lid, or cover mixing bowl with plasticwarp, and refrigerate for at least 6 hours; or up to 24 hours. If marinating longer than 6 hours, stir mixture once or twice to re-coat the vegetables evenly. Re-refirgerate until serving.

Step 4

Serve salad by itself, or on top of sandwiches or burgers, or as a chip or cracker dip. Salad will keep for up to 3 days. As time elapses, vegetables will release their juice and become softer, and amount of liquid in container will increase.
