Boil the potato until tender, then peel and dice into small cubes.
In a skillet over medium heat, add avocado oil and cumin seeds until they sizzle and become 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 diced potatoes, green peas, turmeric, garam masala, sea salt, and black pepper, cooking for 3-4 minutes to meld the flavors.
Cut the whole wheat tortilla into halves and fold each into a cone shape, securing the edge with a toothpick if necessary.
Stuff each tortilla pocket with the turkey and potato mixture, then toast in a dry pan over medium heat until the exterior is golden and crispy.
In a small bowl, whisk together the nonfat Greek yogurt, chopped fresh cilantro, lime juice, and garlic powder to create a creamy chutney.
Serve the warm samosas immediately alongside the chilled yogurt chutney for a high-protein dipping experience.
