Cut each hot dog in half lengthwise, being careful not to cut all the way through; open in center to lay flat. In 12-inch skillet, over medium-high heat in hot oil, place hot dogs flat-side down; cook until lightly browned on both sides, turning once.
Place hot dogs in buns. Top with guacamole and Queso Fresco; drizzle with Chipotle Crema. Serve with additional Chipotle Crema and diced red onions, if desired. Serve with Freír Fries (below).
Freir Fries
Cut Queso de Freír into 3 ½ x ½ x ½ -inch strips.
In deep saucepan, heat 1-inch vegetable oil to 375°F.
Fry cheese strips until well browned on all sides, about 20 seconds.
With slotted spoon, remove to paper towels to drain.
Repeat with remaining cheese strips.
Chipotle Crema
In small bowl combine crema and chipotle peppers; stir to mix well.
