Warm 1 tablespoon of olive oil in a large skillet over medium-high heat until shimmering. Add the ground turkey, spreading it evenly across the pan. Cook for 5-7 minutes, stirring occasionally and breaking it into small pieces with a spatula, until the meat is uniformly browned and no pink remains.

After removing the turkey from the skillet, set it aside on a plate. Pour the remaining olive oil into the skillet and heat over medium. Add the garlic and ginger, stirring continuously until their aroma fills the air, approximately 30 seconds, ensuring they do not burn.

Introduce broccoli, carrots, and bell pepper into the hot skillet. Stir fry over medium-high heat for 5 to 7 minutes, ensuring the vegetables become bright in color and slightly tender. They should retain a bit of crunch, indicating they are cooked but not overly soft.

Place the cooked turkey back into the skillet over medium heat. Add the soy sauce, stirring thoroughly to ensure even coating. Continue cooking for 2-3 minutes, watching as the sauce thickens slightly and the turkey absorbs the flavors, creating a harmonious blend of taste and aroma.

Pour the cornstarch mixture into the skillet over medium heat, stirring constantly to prevent lumps. Continue stirring until the sauce thickens to a glossy consistency and evenly coats the turkey and vegetables, which should take approximately 1 to 2 minutes. Ensure the sauce is smooth and well-distributed.

Pour sesame oil evenly over the stir fry, ensuring it coats the ingredients. Sprinkle red pepper flakes to your taste preference. Stir the mixture thoroughly, allowing the oil and flakes to blend well, enhancing the aroma and ensuring a uniform distribution of flavors throughout the dish.

Sample the stir fry to assess the balance of flavors. If necessary, adjust the seasoning by adding a small amount of salt or pepper. Remember that soy sauce contributes a significant amount of saltiness, so add salt sparingly to avoid overpowering the dish. Aim for a harmonious taste.

Once the stir fry is cooked through and the vegetables are tender-crisp, remove the pan from the heat. Evenly sprinkle sesame seeds over the top, ensuring they cover the dish for a delightful crunch and subtle nutty aroma. Serve immediately to enjoy the best texture.

Carefully transfer the stir fry from the pan to a serving dish, ensuring all ingredients are evenly distributed. Allow it to rest for about one minute, which helps the flavors meld together. This brief pause enhances the overall taste experience before you serve it to your guests.

Once the stir fry is cooked to your desired level of tenderness, transfer it to a serving dish while still hot. For a complete meal, consider serving it over a bed of freshly steamed rice or noodles. This will help absorb the savory sauce and enhance the overall dining experience.
