Divide the beef into four equal portions.
Press each portion thinly onto one side of a tortilla.
Heat a skillet over medium-high heat.
Place the tortilla beef-side down in the skillet and press gently.
Cook for about 3–4 minutes until the beef forms a crispy crust.
Flip the tortilla and place a slice of cheese on the cooked beef.
Cook another 1–2 minutes until the tortilla becomes lightly crispy.
Mix mayonnaise, ketchup, and mustard to create the burger sauce.
