In a bowl, mix the shredded brisket with cumin, smoked paprika, salt, and pepper.
Preheat the Blackstone grill to medium-high heat.
Drizzle 1 tablespoon of avocado oil onto the grill. Add the sliced red onion and bell pepper. Cook, stirring occasionally, until they are softened and slightly charred, about 5 minutes. Remove and set aside.
Lay out the flour tortillas. Sprinkle cheese on half of each tortilla, followed by the seasoned brisket, cooked vegetables, and more cheese. Fold the tortillas over to enclose the fillings.
Brush the remaining avocado oil onto the grill. Place the quesadillas on the grill and cook for about 2-3 minutes on each side, or until the tortillas are golden brown and the cheese is melted.
Remove the quesadillas from the grill. Let them cool for a minute before cutting into wedges. Serve with optional cilantro, sour cream, and salsa.
Notes
Grill Temperature: Preheating the Blackstone grill to medium-high heat ensures that the tortillas will become crispy without burning during the cooking process, which is essential for making delicious
quesadillas.
