1. Prepare marinade: Place green onions, oil, garlic, jalapeno, ginger, sesame oil and lime juice in a large resealable plastic bag. Close and shake to combine. Add pork; turn to coat evenly with marinade. Refrigerate for 4 hours.
2. Prepare sauce: Heat small saucepan over medium heat; when hot add oil and onion. Cook 4 minutes stirring occasionally or until onion is tender. Add ginger and garlic; cook 1 minute or until aromatic.
3. Add undrained tomatoes, rice vinegar, soy sauce, sugar and red pepper flakes to pan; stir to combine. Bring sauce to a simmer; simmer 10 minutes over medium-low heat stirring occasionally. Pour sauce into blender; puree 1 minute or until smooth. Keep warm.
4. Place marinated pork on prepared skewers; discard marinade. Spray nonstick grill pan or large skillet with cooking spray; heat over high heat. When hot add skewered pork to pan; cook 3 to 5 minutes on each side, or until pork is cooked and no longer pink. Serve with dipping sauce.
