The Cubanelle chile is a mild, sweet pepper with just a touch of heat that is very common in the Caribbean. It is light green and almost yellow in color. 
Like an Anaheim or Banana pepper (but slightly sweeter), the Cubanelle is great for frying, stuffing, or incorporating into authentic Cuban, Haitian, Puerto Rican, or Dominican recipes. It can be incorporated into a sofrito along with ají dulce.
