In a large skillet over medium heat, cook 1 lb ground beef or turkey with ½ cup diced onion until browned, about 5-7 minutes.

Drain excess grease. Stir in 1 recipe taco seasoning and ½ cup tomato sauce until meat is coated.

Simmer the meat mixture for 5 minutes.

Heat ½ cup neutral oil in a medium skillet over medium-high heat until shimmering.

Fry 8-12 corn tortillas, about 30 seconds per side, until lightly crisped.

Remove tortillas to paper towels to drain excess oil.

Carefully fold each tortilla to create a taco shape while still warm.

Fill the crispy tortillas with the taco meat and desired toppings like shredded cheese, lettuce, tomatoes, and sour cream.
