Tex-Mex taco on a bun? We’ll try that! Pelonas – a type of Mexican sandwich – is built on a roll that has been deep-fried, giving it a shiny, bald-like appearance. The Pelonas Poblanas in this version are toasted and piled high with refried beans, shredded beef, lettuce and salsa. Instead of crema, a smear of Mayonesa adds tangy creaminess to the finished sandwich. Open wide and take a (giant) bite!
