Heat oil in a large skillet over medium-high heat. Add the onion and frozen riced cauliflower; saute for about 2 minutes. Add the garlic and saute for another minute, stirring often.
Add the ground pork and season with salt. While breaking the meat apart, cook until the pork is no longer pink and is cooked through. Stir in the ginger, rice vinegar, sesame oil, and soy sauce. Remove from heat.
Add sauce ingredients to a small bowl or large measuring cup and whisk to combine.
Remove lettuce leaves that you will be using; rinse and pat dry. Spoon about 2 tablespoons of pork filling mixture onto each leaf (may vary depending on the size of the leaves). Drizzle a bit of sauce over top or serve with sauce for dipping. Top with sliced green onions and serve with lime wedges.
Notes
Filling mixture can be stored in the refrigerator for a few days and reheated in a skillet as needed.
