Method 1: Take a tortilla shell and sprinkle a little bit of cheese over the entire shell. Top with ½ cup of the meat mixture and sprinkle on a little bit more cheese. Top with another tortilla shell. ORMethod 2: Take one tortilla shell and on half of it, sprinkle a little bit of cheese, top with ¼ cup of the meat mixture and sprinkle on a little bit more cheese. Fold the plain half of the tortilla shell over the other half. Heat up a fry pan on low to medium heat.
Add the quesadilla to the dry pan. Do not use any oil. Using the spatula press the top of the tortilla down. Heat for 1-2 minutes or until the bottom tortilla shell is lightly golden brown. Flip and heat for 1-2 more minutes until that side is lightly golden brown. Watch them closely since they cook fast and can burn quickly if you pan is too hot.
Remove from the pan and allow to cool for about 5 minutes before slicing. Use a scissor or a pizza cutter to cut into wedges.
Tastes delicious when served with sour cream, salsa, and/or guacamole.
