Prepare the protein: Heat olive oil in a skillet. Cook chicken, turkey, or beans with taco seasoning until fully cooked and flavorful. Set aside.
Prep vegetables: Chop lettuce, tomatoes, bell peppers, and slice avocado. Mix any sauces or Greek yogurt as desired.
Assemble the wrap: Place a tortilla flat on a clean surface. Center a baked tostada shell on the tortilla, then layer protein, vegetables, cheese (optional), and avocado or yogurt.
Fold the wrap: Bring the edges of the tortilla up to the center, folding evenly to form a hexagonal or round wrap.
Cook until golden: Lightly pan-sear on a non-stick skillet or bake in the oven for 3–5 minutes per side until golden and crisp.
Serve immediately: Slice in half and serve with optional salsa, guacamole, or a side salad.
