Add oil, 2 tablespoons lime juice, taco seasoning and steak to a gallon sized zipper bag. Squish around to get it all coated. Place in refrigerator for at least 4 hours (up to 24hrs) to marinate.
Combine onion, cilantro, salt, jalapeno and remaining lime juice in a small bowl. Stir to thoroughly combine. Place in refrigerator until ready to serve.
Preheat griddle or flattop to high. Once fully hot add marinated meat (with all of the liquid). Allow to cook while moving around frequently with a long spatula. Cook until you no longer see pink. Remove to a plate.
Line out each tortilla on the griddle and cook for around 20 seconds on each side.
Add portion of carne asada and onions to each tortilla. Serve each with a lime wedge.
