Creating the Smashburger Quesadillas is as straightforward as following these easy steps:

1. Prep the Beef: In a bowl, combine ground beef, Worcestershire sauce, garlic powder, onion powder, paprika, salt, and pepper. Mix until well incorporated.
2. Cook the Beef: Heat a skillet over medium-high heat. Add the seasoned ground beef and cook until browned, breaking it apart with a spatula. This should take about 5-7 minutes.
3. Heat the Tortillas: In a separate skillet, warm each flour tortilla over medium heat for about 30 seconds on each side.
4. Assemble the Quesadillas: Take one tortilla, sprinkle half of the shredded cheese evenly across it, then layer half of the cooked beef on top. Sprinkle with more cheese, then place another tortilla on top.
5. Cook the Quesadillas: In the skillet used for the tortillas, cook the quesadilla for about 3-4 minutes on one side until golden brown. Carefully flip to the other side and cook for another 3-4 minutes.
6. Repeat the Process: Repeat steps 4 and 5 for the second quesadilla.
7. Rest and Slice: Remove the quesadillas from the skillet and let them rest for a minute. Cut each into wedges.
8. Prepare Toppings: Serve with shredded lettuce, diced tomato, avocado slices, sour cream, and salsa on the side.

This step-by-step guide ensures that your Smashburger Quesadillas are both delicious and satisfying.
