Preheat your oven to 425 degrees Fahrenheit. Line 2 baking sheets with parchment paper and spray with nonstick cooking spray.
In a skillet over medium-high heat add in the ground beef and onion and cook until meat has browned. Drain any excess fat.
Next, lower the heat to medium and add in the taco seasoning, water, garlic, lime juice, diced green chilies, salt and pepper and mix.
Once the water has evaporated, add in 1 cup of cheddar cheese and stir until everything has combined.
Doing 8 at a time, wrap the tortillas in a damp paper towel and microwave them for a minute, flipping them halfway through.
Then place a tortilla on your prepared baking sheet, add ⅛-¼ cup of the ground beef mixture to one half of the tortilla and sprinkle on a little of the remaining cheddar cheese. Do not fill them too much or they will ooze out the sides.
Fold the tortilla more than halfway over as it will peel back slightly while baking in the oven. Then lightly brush the top of the tortilla with olive oil. Repeat until one baking sheet is full.
Bake in the oven for 15-20 minutes until crispy.
Finally, serve with your favorite toppings and enjoy!
