Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the turkey and cook until almost cooked through, about 5-6 minutes.
Push the turkey to one side of the pan and add the onion and remaining tablespoon of oil. Cook for 3-4 minutes, stirring occasionally.
Add shredded carrots, garlic, and ginger and cook for 2 minutes, stirring frequently.
Pour in the chicken broth and scrape any brown bits from the bottom of the pan.
Add cabbage, soy sauce or tamari, rice vinegar, salt, and black pepper. Stir well and cover.
Reduce heat to medium-low and cook for 12-15 minutes, or until cabbage is tender to your liking.
Remove from heat and stir in toasted sesame oil.
Serve over cooked white rice if desired, topped with green onions, toasted sesame seeds, and sriracha mayo.
