Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Peel and dice the Yukon gold potato into small 1/4-inch cubes. Boil in a small pot of water for 5-7 minutes until tender, then drain and set aside.
In a non-stick skillet over medium heat, add the ground turkey, minced garlic, and minced ginger. Cook until the turkey is browned and cooked through.
Stir in the boiled potatoes, green peas, cumin seeds, garam masala, turmeric, sea salt, and black pepper. Sauté for 2-3 minutes to toast the spices, then remove from heat.
Cut the whole wheat tortilla into three long, equal strips. Place a portion of the turkey and potato mixture at one end of a strip and fold it diagonally into a triangle shape, tucking the end in to seal.
Place the samosas on the prepared baking sheet and lightly brush the tops with avocado oil.
Bake for 12-15 minutes, flipping halfway through, until the edges are golden brown and crispy.
While the samosas bake, finely chop the cilantro and stir it into the Greek yogurt to create a zesty dipping chutney.
Serve the warm samosas immediately with the cilantro-yogurt dip on the side.
