Creating amazing Filipino-Style BBQ Chicken Legs is straightforward if you follow these simple steps:

1. Prepare the Marinade: In a mixing bowl, combine soy sauce, vinegar, brown sugar, minced garlic, black pepper, vegetable oil, calamansi juice, and paprika.
2. Marinate the Chicken: Place chicken legs in a resealable plastic bag or shallow dish. Pour the marinade over the chicken, ensuring they are well coated. Seal the bag (or cover the dish) and refrigerate for at least 30 minutes, preferably overnight for maximum flavor.
3. Preheat the Grill: If grilling, preheat your grill to medium-high heat (about 350°F to 400°F). Alternatively, you can use an oven with a broiler setting.
4. Prepare the Chicken for Cooking: Remove the chicken from the marinade and allow excess marinade to drip off. Discard the remaining marinade.
5. Grill the Chicken: Place chicken legs on the grill and cook for about 30-40 minutes. Turn occasionally, basting with leftover marinade if desired, until they reach an internal temperature of 165°F and have an attractive caramelized color.
6. Broil (if using an oven): Place the chicken legs on a baking sheet lined with foil. Broil for 25-30 minutes, turning every 10 minutes until golden brown and cooked through.
7. Let Rest: Once cooked, remove the chicken from the grill or oven and allow it to rest for about 5-10 minutes. This helps lock in the juices.
8. Garnish and Serve: Sprinkle chopped scallions over the chicken for a fresh, colorful touch.

These steps will guide you effortlessly in creating delectable Filipino-Style BBQ Chicken Legs.
