Peel and dice the russet potato into small cubes, then boil in water until tender; drain and set aside.
Heat olive oil in a skillet over medium heat and add cumin seeds until they sizzle.
Add the ground turkey to the skillet, breaking it apart and cooking until browned and fully cooked through.
Stir in the turmeric, garam masala, sea salt, black pepper, cooked potatoes, and frozen peas, cooking for 3 minutes to blend flavors.
Preheat your oven to 400°F and line a baking sheet with parchment paper.
Cut the whole wheat tortilla into three long strips. Place a portion of the turkey and potato mixture at one end of a strip and fold into a triangle shape, sealing the edge with a drop of water.
Place the samosas on the baking sheet and bake for 10-12 minutes until the edges are golden and crunchy.
While baking, prepare the chutney by blending the Greek yogurt, fresh cilantro, fresh mint, and lime juice until smooth.
Serve the hot samosas immediately with the chilled yogurt chutney on the side.
