Add vinegar, water, sugar, and salt into a microwave safe dish then microwave on high for 1 minute. Stir until sugar is completely dissolved then pour over carrots, stir to combine, and refrigerate. Can be made a week ahead of time.
For the Caramelized Ground Pork:
Place 2 layers of paper towel on a large plate then set aside. Heat oil in a large wok or skillet over high heat. Add ground pork, shallot, garlic, ginger, salt, and pepper to taste then saute until pork is just barely cooked through, breaking it up as it cooks. Add brown sugar and fish sauce to the skillet then stir to combine. Spread the pork into an even layer in the bottom of the wok or skillet then saute for 2 minutes - DO NOT DISTURB OR STIR THE PORK as it caramelizes. Stir then spread the pork into an even layer again and cook for 2 more minutes, undisturbed. Continue cooking then stirring in two minute increments - leaving the pork alone as it cooks and caramelizes - until the pork is brown and caramelized. You may need to cook in 1 minute increments near the end to prevent the sugar from burning. Scrape the caramelized pork onto prepared paper towel lined plate to drain then set aside.
For the Cilantro Lime Cauliflower Rice:
Get out a large serving bowl then set aside. Place wok or skillet back over high heat then add the oil. Once the oil is hot, add the cauliflower rice, season with salt and pepper, then stir fry until the cauliflower is crisp tender, 3-4 minutes. Add the lime juice and chopped cilantro then stir to combine. Scrape the cauliflower rice into the serving bowl then set aside.
For the Green Curry Drizzle:
Place the wok or skillet back over medium-high heat. Add the curry paste then saute for 30 seconds, scraping/flattening/stirring it with a spatula. Add the coconut milk, chicken broth, and sugar then stir until smooth and bring then sauce to a simmer. Turn the heat down to medium then simmer until the sauce is slightly thickened and reduced, 3-4 minutes. Squeeze in a little lime juice to taste.
To assemble:
