Preheat oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
In a large skillet over medium heat, add avocado oil and toast the cumin seeds until they become fragrant and start to pop.
Add the ground turkey, minced garlic, and grated ginger to the skillet, breaking up the meat with a spatula until it is browned and cooked through.
Stir in the diced boiled potatoes, green peas, garam masala, turmeric, sea salt, and black pepper, cooking for 3 minutes to meld the flavors.
In a small bowl, whisk together the Greek yogurt, chopped cilantro, and lemon juice to create a high-protein dipping chutney.
Cut the phyllo dough into long strips and place a spoonful of the turkey and potato mixture at one end of each strip.
Fold the dough over the filling in a triangular pattern until the strip is finished, then place the samosas on the baking sheet.
Lightly mist the samosas with a touch of oil and bake for 12-15 minutes until the exterior is perfectly golden and crunchy.
