SEASON STEAK: In a small bowl, combine 1 teaspoon kosher salt, ½ teaspoon fresh ground black pepper, ½ teaspoon garlic powder, ½ teaspoon chili powder, and ½ teaspoon cumin. Pat the seasoning evenly onto both sides of the 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 the flour tortillas in a dry skillet or microwave for 10 to 15 seconds until pliable.
ASSEMBLE: Divide the steak evenly among the tortillas. Top each with French fries, shredded cheddar cheese, guacamole, and sour cream.
ROLL: Fold in the sides of each tortilla, then roll tightly into burritos.
SERVE: Serve immediately, garnished with fresh cilantro.

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.
