Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Heat the avocado oil in a large skillet over medium heat and toast the cumin seeds for 30 seconds until fragrant.
Add the finely diced gold potatoes to the skillet and sauté for 5-7 minutes until they begin to soften.
Incorporate the ground turkey into the pan, breaking it up with a wooden spoon, and cook until browned and fully cooked through.
Stir in the frozen peas, turmeric, garam masala, sea salt, and black pepper, then remove the mixture from heat to cool slightly.
Lay out the phyllo sheets on a clean surface, cut them into 3-inch wide strips, and place a tablespoon of the turkey filling at the base of each strip.
Fold the phyllo over the filling in a triangular pattern, similar to folding a flag, and place the samosas on the prepared baking sheet.
Bake for 12-15 minutes, turning halfway through, until the pastry is golden brown and crispy.
In a small bowl, whisk together the Greek yogurt, chopped cilantro, and lemon juice to create a bright chutney for dipping.
