Gather all your ingredients. Preheat your oven to 375°F (190°C). Line a baking sheet with Reynolds Wrap Non-Stick Foil for easy cleanup.
In a skillet over medium heat, spray a light coat of olive oil. Add minced garlic and onion, sauté until fragrant and translucent.
Add ground turkey, breaking it up with a spatula. Season with garlic powder, cumin, kosher salt, and tomato paste. Pour in water and cook until browned and cooked through, about 5-7 minutes.
While turkey is cooking, halve and seed jalapeno peppers, removing membranes for milder flavor.
Mix softened cream cheese with chopped cilantro until smooth and creamy.
On the prepared baking sheet, spread a layer of tortilla chips. Top with ground turkey mixture, then dollop cream cheese mixture on top. Place halved jalapenos over the nachos, then sprinkle shredded cheddar cheese.
Bake in the preheated oven for 15-20 minutes, until cheese is melted and bubbly. Watch carefully to avoid burning.
Remove from oven and garnish with sliced scallions, additional chopped cilantro, pico de gallo, black olives, and drizzle with sour cream and water mixture. Serve hot.
