Preheat your oven to 400°F and line a baking sheet with parchment paper.
Boil the diced gold potato in a small pot of water until tender, then drain and set aside.
Heat avocado oil in a large skillet over medium heat and toast the cumin seeds until fragrant.
Add the ground turkey to the skillet, breaking it apart with a spatula and cooking until browned and fully cooked through.
Stir in the turmeric, garam masala, sea salt, black pepper, cooked potatoes, and green peas until well combined.
Lay out the phyllo dough sheets on a clean surface and cut them lengthwise into long 3-inch wide strips.
Place a generous spoonful of the turkey and potato mixture at the bottom end of a phyllo strip.
Fold the corner of the strip over the filling to form a triangle, and continue folding diagonally like a flag until the strip is finished.
Place the samosas on the prepared baking sheet and bake for 15-18 minutes until they are golden brown and crispy.
While the samosas bake, blend the Greek yogurt, fresh cilantro, and lime juice in a small food processor until smooth to create the chutney.
