Add the shrimp and cook, stirring frequently, for 2-3 minutes, until the shrimp are no longer translucent, turn pink and begin to curl.
Add salsa and let simmer over lowest heat for about ten minutes longer, stirring frequently. You'll want the shrimp to soak up the flavor from the spicy salsa, without overcooking.
Meanwhile, warm the tortillas according to directions on the package. When shrimp is done, spoon shrimp mixture into each tortilla and top with queso blanco. Garnish with fresh cilantro, if desired.
