Combine all of the marinade ingredients in a small saucepan and bring to a boil over medium-high heat. Lower the heat to low and simmer for 20 minutes, or until its been reduced by about half.
When the marinade has come to room temp, add the turkey meatballs, cauliflower, and onion. Let sit in the fridge for at least half an hour (longer is ok)
In the meantime, cook the rice according to the package directions.
Preheat the oven to 400°F
Add the ingredients, in rotating order to the skewers. Place them on a parchment-lined baking sheet, a little ways apart.
Bake 30 to 35 minutes, until the turkey is cooked through and the cauliflower is crisp on the outside, and tender on the inside.
Of, if you find the cauliflower skewing to be challenging, nothing bad would happen if you just baked all of the parts separately
Serve the turkey, cauliflower, and onions on top a bed of wild rice
