Season the ground beef with seasoned soy sauce and taco or beef seasoning to taste. Mix well.

Heat a little olive oil in a skillet and cook the beef until fully cooked, about 5-7 minutes.

To make the salsa, roast the tomatoes, onion, garlic, and serrano peppers (cutting them first makes roasting easier). Blend them together and add salt to taste.

To serve, warm the tortillas, add the beef, top with some salsa, and serve with lime wedges.
