In a large skillet over medium heat, brown the ground beef until no longer pink, about 5-7 minutes. Drain excess fat, then add diced onions and taco seasoning. Cook for another 3-5 minutes until onions soften.

Preheat your oven to 350°F (175°C) and grease a 9x13-inch baking dish. Unroll the first batch of crescent roll dough across the bottom, pressing seams together.

Spread the cooked beef mixture evenly over the prepared dough. Sprinkle the shredded cheddar cheese on top.

Unroll the second batch of crescent roll dough over the cheese layer and seal edges by pinching.

Bake in the preheated oven for 20-25 minutes until golden brown and cheese is bubbling.

Let it cool for a few minutes, then top with fresh cilantro or green onions. Serve warm with optional toppings.
