Step 1: Prepare the Filling : In a medium bowl, combine softened cream cheese, chopped crab meat, green onions, soy sauce, and garlic powder. Mix until smooth and well combined.

Step 2: Fill the Wontons : Place a wonton wrapper on a clean surface. Spoon about 1 teaspoon of the crab mixture into the center. Moisten the edges of the wrapper with water and fold into a triangle or bring corners together to form a pouch. Press edges firmly to seal. Repeat with remaining wrappers and filling.

Step 3: Heat the Oil : In a deep skillet or pan, heat vegetable oil over medium-high heat to 350°F (175°C). The oil should be enough to submerge the wontons halfway.

Step 4: Fry the Crab Rangoon : Carefully place 4-5 wontons in the hot oil. Fry for 2-3 minutes per side, or until golden brown and crispy. Remove with a slotted spoon and drain on paper towels. Repeat with remaining wontons.

Step 5: Prepare the Sweet Chili Sauce : In a small bowl, mix sweet chili sauce, rice vinegar, and sesame oil. Adjust sweetness or tanginess according to taste.

Step 6: Serve : Serve hot Crab Rangoon with the sweet chili sauce on the side for dipping.
