Mix sour cream and taco seasoning mixture together and put a thin layer in the center of the large tortilla. Set extra sour cream and seasoning mixture to the side.
Lay the large tortilla on a flat surface and add a layer of the sour cream and taco seasoning mixture in the middle leaving a couple inches on all sides.
Add a small amount of ground beef on top of the sour cream mixture.
Top with chunky salsa, guacamole, jalapenos, cilantro and shredded cheese.
Top with the small tortilla and fold the large tortilla around the edges to close up the sides.
Lay closed edges of the tortilla face down in a preheated large skillet and toast until golden-brown on medium heat. Flip and repeat of the other other side.
Remove from heat and cut in half.
Serve immediately with extra chunky salsa or by itself!
