In a small dish, whisk the Chipotle Pepper Sauce, tomato paste, and 2 Tbs. water. Heat the oil in a 12-inch skillet over medium-high heat. Add the onion and cook, stirring very frequently, until lightly browned, 3 to 5 minutes. Add the garlic, chili powder, and cumin and cook until fragrant, about 30 seconds.
Add the turkey and sprinkle with 1 tsp. salt. Cook, using a wooden spoon to break the meat into small pieces, until just cooked through, about 3 minutes. Stir in the tomato paste mixture and let cook until the liquid is almost absorbed, 1 to 2 minutes.
Off the heat, stir in the cilantro and season to taste with more salt if needed. Serve folded in the tortillas with your favorite taco toppings.
