If using rice noodles, cook them according to the package instructions, then rinse under cold water and set aside.
Preheat oven to 450F or 425F convection. Line a baking sheet with parchment paper. Drizzle about 2 tablespoons olive oil all over the baking sheet and use your hands or a brush to spread around evenly.
In a large bowl, add the meat, rice, scallions, soy, sesame, garlic, and salt and use your hands to thoroughly combine. Form into about 16 golf ball-sized meatballs and place on the prepared baking sheet (wet your hands to help keep the meat mixture from sticking to your hands).
Roll the meatballs all around in the oil to lightly coat (this will help them get golden brown). Bake for 15 minutes, then flip and bake for 7-10 more minutes or until golden on the bottom.
In a jar with a lid, add the oil, orange juice, vinegar, ginger, tahini, soy sauce, and salt and shake vigorously until smooth.
(Only assemble the amount of salad you know you’ll eat, as it does not keep well as leftovers). Add greens, carrot, cucumber, tomatoes (if using), and rice noodles (if using) to a large bowl or salad bowl. Pour ⅔ of the dressing over top and toss to coat. Serve topped with meatballs, herbs, and seeds. Drizzle the remaining dressing over top.
