Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Boil the diced Yukon gold potato in water until tender, about 8-10 minutes, then drain and set aside.
In a large skillet over medium heat, add the avocado oil and cumin seeds, toasting until fragrant.
Add the ground turkey to the skillet and cook until browned, breaking it into small crumbles.
Stir in the turmeric, garam masala, sea salt, black pepper, cooked potatoes, and frozen peas, mixing well to combine the flavors.
Place a spring roll wrapper on a clean surface and cut into wide strips; place a portion of the turkey mixture at one end and fold into a triangle shape.
Lightly brush the samosas with a tiny bit of oil and bake for 12-15 minutes until the edges are crispy and golden brown.
While the samosas bake, prepare the chutney by whisking the Greek yogurt, chopped cilantro, mint, and lime juice in a small bowl.
Serve the hot samosas immediately with the cooling yogurt chutney on the side.
