Thoroughly wash, peel and dice the jicama. Preheat the oven to 425 degrees. Place the jicama in and even layer in a 3-quart casserole dish. Pour enough water into the dish to fully cover the jicama. Cook in the oven for 8 to 10 minutes until the jicama is slightly softened.
Remove jicama from the oven. Pour jicama into a colander. Immediately rinse with cold water until the jicama has cooled to room temperature then drain the water out as much as possible. Place the drained jicama into a large mixing bowl. Add all the vegetables and the dry seasonings then stir to fully combine.
Stir in the wet ingredients until fully combined and all the vegetables are fully coated with the dressing. If desired fold in some cooked and crumbled bacon or add-ins of choice. Cover the salad and refrigerate for at least 30 minutes before serving. Can be made up to 24 hours in advance
