Combine imitation crab meat or real crab meat, cream cheese, green onion, soy sauce, sesame oil (if not allergic), Worcestershire sauce, sugar, garlic powder, and black pepper in a mixing bowl.
Lay out the wonton wrappers on a clean surface.
Place a small amount of the filling in the center of each wrapper.
Moisten the edges of the wonton wrapper with water.
Fold the wrapper in half, forming a triangle, and press the edges to seal.
Optionally, fold the two bottom corners of the triangle towards each other for a traditional Crab Rangoon shape.
In a deep pan, heat the avocado oil or neutral tasting oil to 350°F (175°C).
Carefully place the sealed wontons in the hot oil and fry until golden brown (usually 2-3 minutes per side)
Use a slotted spoon to remove the Crab Rangoon from the oil and place them on a paper towel to drain excess oil.
Arrange the Crab Rangoon on a serving plate and present them with a side of sweet Thai Chili sauce.
