Creating Smashburger Quesadillas is straightforward if you follow these simple steps:

1. Cook the Beef: Heat a skillet over medium heat. Add the ground beef and cook until browned, about 5-7 minutes.
2. Season the Beef: Drain excess fat, then add the taco seasoning to the beef. Stir well and cook for an additional 2 minutes.
3. Prepare the Tortillas: In another skillet, heat olive oil over medium heat. Place one tortilla in the skillet.
4. Layer Ingredients: On one half of the tortilla, layer a portion of the cooked beef, followed by a generous amount of cheddar cheese, diced tomatoes, and chopped green onions.
5. Fold the Quesadilla: Fold the tortilla in half to cover the filling. Cook for 3-4 minutes, until the bottom is golden brown and the cheese has melted.
6. Flip and Cook: Carefully flip the quesadilla and cook the other side for another 2-3 minutes until golden brown.
7. Repeat: Remove the cooked quesadilla and place it on a cutting board. Repeat the process with the remaining tortillas and filling.
8. Slice: Once all quesadillas are cooked, slice them into wedges for serving.
9. Serve Warm: Serve immediately with sour cream and salsa on the side.

These steps will guide you in creating these incredible Smashburger Quesadillas effortlessly.
