Fusion between Chinese and Tex-Mex cuisines is somewhat new. The Cantonese cuisine that brought America egg rolls and wontons led to the popular 1990s dish of “Southwestern eggrolls.” 
 
“Texas wontons” is not a currently popular dish, but the recipe for “Texas Wontons with Spicy Guacamole and Sour Cream” is copied on many websites. Italian sausage is used in the recipe, along with Tex-Mex ingredients such as cayenne, chili paste, and cilantro.
 
Recipes for “Tex-Mex Wontons” appear to be more frequent and include ground beef, cheddar cheese, and refried beans in the wonton skins.

TEX-MEX Wontons
 
This recipe is pretty big so if you ain’t throwing a party you may want to cut down a bit.  It makes about 90 wontons.
 
1   lb   groud beef
1/2 C   Cheddar Cheese, shredded
1/2 C   onions, chopped fine
2   T   catsup
1/4 C   chopped chiles (your choice)
3   t   chili powder (more or less)
1   15oz can refried beans
1/2 t   ground cumin
8   doz wonton skins
oil for frying
Taco Sauce or Salsa for dipping
 
Brown Beef and onions, drain.
Stir in refiried beans, mix thoroughly.
Mix remaining ingredients together, then add it all to the beef and bean mixture.  Mix well.
Fill each skin with about a tablespoon or so of the mixture.
Fold over and seal skins. 
Fry about 1 minute per side, drain on paper towel and serve warm with salsa or other sauce.  Actually, I really like a little dollop of sour cream with the wontons along with the salsa.
