Heat sesame oil over medium low in a large skillet; add garlic and ginger. Cook until aromatic, 1 minute. Add mushrooms, stir and cover so they release some of their moisture, 2-3 minutes. Uncover and cook, stirring until browned, 3 to 4 minutes.
Add veggie slaw and cook until semi-soft, 3-4 minutes. Add soy sauce and sweetener; cook until sticky and caramelized.
Transfer to a shallow dish and cool completely. Wipe out the pan while it is still warm.
While filling cools, prepare dipping sauce: In a small bowl combine remaining sesame oil, ginger, soy sauce, sweetener, sriracha and rice vinegar.
Roll the spring rolls: Spray the same pan with cooking spray and keep on medium-low heat. Working individually, dip a spring roll wrapper in warm water until it is pliable, 30 to 45 seconds. Lay on a clean surface, I found a damp clean towel works well. Add one strip of salmon in the center and top with two heaping tablespoons of chilled vegetable filling. Roll like a burrito, folding in the sides after the first rollover. Sear, seam side down– which should, in turn, also be the side that the salmon is on.
Sear until crisp, 4-5 minutes per side. Try to avoid letting the rolls touch each other while in the pan, this could cause them to rip!
Notes
Yields: 9 rolls and ⅓ cup dipping sauce
Pro Tip: I found using a damp clean kitchen towel as my surface worked perfectly and made the rice paper easy to work with.
Don't let the spring rolls tough when cooking, they will stick to each other.
