Preheat the oven to 375. Toss mixed vegetables in avocado oil, salt, and pepper. Bake for 30 minutes.
While vegetables are roasting, thaw the shrimp in a large bowl of cold water. Change out water every 10 minutes until thawed.
Combine all the sauce ingredients in a small bowl and set aside.
Next, add frozen caulirice to a small pot and steam over medium heat until tender.
In a skillet, add thawed shrimp with ¾ of the sauce and stir to coat. If you prefer a thicker sauce, add 1 tsp of arrowroot flour to the sauce. Heat over medium until warmed through.
Once vegetables are tender, plate as desired. Drizzle the remaining sauce over each plate and garnish with extra parsley or lemon. Enjoy!
