Preheat your oven to 425°F and line a large baking sheet with parchment paper.
Slice the russet potato into thin, uniform wedges and toss them in a bowl with avocado oil, sea salt, and black pepper.
Spread the potato wedges in a single layer on the baking sheet and roast for 25-30 minutes, flipping halfway through, until golden and crisp.
While the potatoes roast, season the chicken breast with lime juice, cumin, chili powder, and garlic powder.
Heat a grill pan or skillet over medium-high heat and cook the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
Let the chicken rest for 5 minutes before dicing it into small, bite-sized cubes.
Plate the crispy roasted potatoes and top them immediately with the diced chicken.
Garnish your loaded fries with a dollop of Greek yogurt, fresh pico de gallo, and chopped cilantro before serving.
