1/2cuppico de gallodrained (either store-bought or homemade)
2 1/2cupsshredded Mexican Blend Cheese
Preheat oven to 400 degrees F. Line a baking sheet with parchment paper.
Place potatoes, in one layer, on the prepared baking sheet. Bake until easily pierced with a fork, 25 to 30 minutes. Remove from oven and let cool slightly, about 10 minutes.
Slice each potato crosswise about 1 inch from the bottom (widest part) of the potato. Using a small spoon, gently scoop out the inside (white part) of the potato, into a medium bowl; set potato bites aside. Add sour cream, butter, and milk to bowl with potato. Sprinkle with a little salt and pepper. Mash until smooth and combined. Set aside.
Heat olive oil in a large skillet over medium heat. Add ground beef and cook, stirring often, until beef is browned and no longer pink, about 10 minutes. Sprinkle taco seasoning evenly over the top. Add pico de gallo. Remove from heat and fold beef mixture into mashed potato mixture along with 1 cup cheese and chives; sprinkle with salt and pepper to taste.
Spoon potato and meat mixture into hollowed-out potato bites and place on a parchment paper-lined baking sheet. Sprinkle potato skins with remaining 1 cup cheese and place in the preheated oven; bake until cheese is melted and potatoes are hot, about 20 minutes. Serve topped with sour cream, remaining pico de gallo, and cilantro.
