To make the salsa: Finely chop tomatillos, tomato, onion and cilantro in a food processor or blender. Add chopped green chilies and white wine vinegar. Add salt to taste, cover and refrigerate 6 hours.
To make the eggroll filling - Fry chorizo and onion in a medium skillet until chorizo is crumbly. Drain well. Add beans, cheese, cumin and cayenne pepper. Stir until cheese is melted. Let cool to room temperature.
To assemble: Place 1 teaspoon of filling close to one corner of wonton wrapper. Fold corner over filling to cover. Fold over left and right corners. Brush sides and top of triangle with water. Roll, sealing corner. Place on a baking sheet and cover while rest of wontons are filled.
In a deep pan, pour vegetble oil to a depth of 1 inch and heat oil to 360 degrees. Fry 7-8 filled wontons at a time until golden brown - approximately 2-3 minutes. Remove and drain wontons on paper towels. Keep warm in a 200 degree oven until all are done. Serve warm with salsa and sour cream, if desired.
