In a large nonstick skillet over medium high heat, drizzle in (1) teaspoon of oil, add the ground beef and cook until brown. Drain excess fat. Mix in taco seasoning and beef broth (or water) and cook until mixture thickens, about 3-4 minutes. Taste and season with salt and pepper, if needed. Set aside to cool to room temperature.
Place a burrito sized tortilla down on a clean work surface. Spoon a portion of the ground beef into the center of the tortilla. Spread about 2-3 tablespoons of queso cheese sauce over the ground beef. Top with a tostada and spread over 2 tablespoons of sour cream. Place a layer of shredded lettuce and diced tomatoes over sour cream. Top with 1/2 cup of cheese. For a extra cheesy crunchwrap, add up to 2/3 cup of cheese.
Place a street sized tortilla on top of the cheese layer and fold the edges of the large tortilla over the smaller tortilla to form a wrap.
In a medium non-stick skillet over medium-low heat, drizzle in remaining oil. Place the wrap seam side down to brown and toast for 3 minutes. Flip and toast the top of the wrap for 2-3 minutes or until golden brown. Repeat with remaining wraps. Serve immediately while still hot.
