To make these tacos, start by preheating your oven to 400F. While the oven heats, place a large skillet on the stove over medium heat.
Once the pan is hot, add the ground beef and let it cook for 3-4 minutes, until it begins to brown.
Next, add the diced onion, garlic powder, and black pepper. Continue sautéing for another 3-4 minutes, until the onions soften and the beef is fully browned.
Once everything is cooked through, stir in the canned chili and ½ cup of the shredded cheddar cheese. Mix until the filling is well combined, then remove the skillet from the heat.
Line a baking sheet with parchment paper. Fill each tortilla with a generous scoop of the chili-beef mixture and top with an additional 1-2 tablespoons of cheddar cheese.
Fold each tortilla closed and arrange them on the prepared sheet pan. Lightly spray the tops of the tortillas with cooking spray of choice.
Bake for 12 minutes, then switch the oven to broil and cook for another 2 minutes, just until the tops are golden and brown. Be careful that they don't burn!
Remove from the oven, garnish with chopped parsley, and enjoy!
