Place ground beef in a large non-stick skillet. Add chopped onion, garlic powder, taco seasoning, and water to beef. Stir, cook and crumble beef over medium-high heat. Bring mixture to a boil, then reduce heat to low. Simmer for about 10 minutes.
Meanwhile, fold flour tortillas in a taco shape and place side by side in a 9x13 inch baking pan. (I fit 6 down the center and 2 on each side) Divide the taco meat evenly among the tortillas in pan.
Place pan in the preheated oven. Bake 5 to 8 minutes or until tortillas are heated through.
Carefully remove from oven and fill tacos with all your favorite taco toppings. Enjoy!
