In a large bowl, combine garlic, soy sauce, sesame oil, and ginger. Mix well. To the sauce, add the coleslaw mix, beansprouts, and mushrooms. Toss well to coat. Allow to marinate for 5 minutes before tossing again.
Lay out two overlapping spring roll wrappers like a diamond. Place a spoonful of the vegetable mixture in the center.
Mix the cornstarch and water with a fork whisked until smooth. Set aside. Fold the sides of the wrapper over the filling, then fold the bottom over and roll tightly. Use the cornstarch-water mixture to seal the edge.
Preheat the air fryer to 375°F (190°C) for 5 minutes. Lightly coat the spring rolls with olive oil cooking spray and place them in the air fryer basket, making sure they are not touching.
Air fry for 10-12 minutes, turning halfway through, or until they are golden brown and crispy to your liking. Serve with your favorite dipping sauce.
Spring Roll Sauce - 1/4 c soy sauce + 1/2 c ketchup + 1/4 c white vinegar + 2-3 tbsp cornstarch to thicken + 2-3 tbsp water + 1/2 tsp red pepper flakes is what you need. Put a small saucepan over the stovetop on medium/high heat. Whisk together all ingredients except the water and cornstarch (that is to thicken at the end). Heat until it begins to bubble.Start with whisking in a small cup 2 tbsp cornstarch + 2 tbsp water until smooth and pour that into sauce. Allow to bubble and thicken. If you want it thicker do the same with the remaining 1 tbsp cornstarch + water until thicker.Remove from heat, it will continue to thicken as it cools as well
