SEASON STEAK: In a small bowl, combine 1 teaspoon kosher salt, 1/2 teaspoon fresh ground black pepper, 1/2 teaspoon garlic powder, 1/2 teaspoon chili powder, and 1/2 teaspoon ground cumin. Pat the seasoning evenly onto both sides of 1 1/2 pounds flank steak.
SEAR: Heat 1 tablespoon extra virgin olive oil in a large skillet over high heat. Add the flank steak and cook for 3 to 4 minutes per side, until well browned and cooked to your desired doneness.
REST AND SLICE: Transfer the steak to a cutting board and let rest for 5 minutes. Slice thinly against the grain, then cut into bite-sized pieces.
WARM TORTILLAS: Warm 3 large flour tortillas in a dry skillet or microwave for 10 to 15 seconds until pliable.
ASSEMBLE: Divide the steak evenly among the tortillas. Top with 2 cups frozen French fries, cooked until crispy, 1 cup shredded cheddar cheese, 1 cup guacamole, and 1/2 cup sour cream.
ROLL: Fold in the sides of each tortilla, then roll tightly into burritos.
SERVE: Serve immediately, garnished with Fresh cilantro leaves.

For a crisp exterior, warm in a skillet for 1 to 2 minutes per side.Ingredient Note: Flank steak is lean and flavorful. Skirt steak works equally well if available.
