In a mixing bowl, combine ground beef, taco seasoning, chopped onion, and parsley.
Mix until evenly blended.
Lay one tortilla flat on a clean surface.
Spread a thin, even layer of the raw beef mixture over the tortilla, going right to the edges.
Roll the tortilla up tightly from one end.
Slice into 1–1.5 inch thick rounds using a sharp knife.
Arrange the rounds flat on the baking sheet.
Brush the tops lightly with olive oil or melted butter.
Bake for 18–22 minutes, flipping halfway, until beef is fully cooked and tortillas are golden brown.
Serve warm with salsa, sour cream, or your favorite dipping sauce.
